Frequently asked questions.

We're a smart textile startup based in Woodinville, WA. We design and manufacture pressure-sensitive sensor products built on conductive textiles, polymers, and technical embroidery. Beyond our off-the-shelf products, we work with OEMs to create custom pressure-sensitive smart textile solutions — including custom hardware and software — tailored to specific applications. Our consumer products also pair with popular platforms like Home Assistant to deliver real-time presence detection and alerts.

Our sensors are fabric-based rather than rigid. They're thin, flexible, and designed to be discreet. Because they use a resistive textile grid, they can detect analog pressure — making them highly valuable for presence vs. absence detection. While the underlying technology is capable of more, reliable, real-time presence detection is what our customers find most compelling and useful day to day.

No. Our products are not washable. They are designed to be water-resistant and, in some configurations, waterproof — but they are not safe for machine washing or submersion.

Yes. ASC was granted a U.S. patent (Ser. No. 18/632,874) in early 2026 covering the core sensing technology.

Both TrampleTek Blue and SlumberTek are available at asc.com. Orders over $150 ship free domestically (U.S.).

Yes, international shipping is available to most countries. Rates and delivery times vary by destination. The site will calculate shipping at checkout.

Yes, if you catch it before the label is created — reach out to shop@asc.com right away and we can update it.

Reach out to shop@asc.com with a description of the issue and photos if relevant. If the device is confirmed defective and within the 1-year warranty we'll replace it.

Yes. If within the first 30 days SlumberTek or TrampleTek Blue doesn't work for your setup and we can't fix it together, we'll buy it back and cover the return shipping. We prefer to get devices back so we can refurbish or recycle the electronics rather than let them go to waste. Reach out to shop@asc.com to initiate.

No. Neither TrampleTek Blue nor SlumberTek captures any video, audio, or imagery. They only detect pressure. No identity is captured.

If you're using Home Assistant, your data stays entirely local on your own network — nothing goes to ASC servers. If you use the ASC app, data is processed through our secure cloud infrastructure. We do not sell user data.

TrampleTek Blue is a durable, discreet pressure-sensitive floor mat built from advanced textile sensors and technical embroidery. It has a built-in ESP32 Wi-Fi/Bluetooth chip and integrates with Home Assistant (or can run standalone with the optional BLE wall socket). When someone or something steps on it, it fires an event you can use to trigger any smart home automation you can imagine.

Customers have used it for: front door arrival detection, pet door notifications, puppy potty training, car alignment in the garage, kitchen sink lighting automation, workshop tool activation, Halloween animatronic triggers, package delivery detection, laundry weight estimation, research experiments, and commercial foot traffic counting. The community constantly comes up with creative applications — check the project-sharing channel on our Discord for inspiration.

Yes. TrampleTek Blue can detect objects down to approximately one pound, so cats and similarly sized animals are well within its detection range.

TrampleTek Blue is designed for indoor use and can handle light moisture. Extreme conditions — heavy rain, flooding, or prolonged exposure to extreme heat — are not recommended.

For Home Assistant users: a computer with Chrome (for the web flasher), your Wi-Fi credentials, and an existing Home Assistant installation. For standalone use: the optional BLE wall socket add-on, which lets you use it without a full home automation system.

Use our web-based flasher — no software to install. Connect TrampleTek Blue to your computer via USB, open the firmware install page in Chrome, and follow the prompts. There's also a YouTube walkthrough at youtube.com/@AppliedSensorCo. Note: the web flasher requires Chrome or Edge — it will not work in Firefox or Safari.

Probably not. When TrampleTek Blue ships, it has QA firmware that lights up to indicate pressure. Once you flash the Home Assistant firmware, the LED no longer lights up during normal operation — this is expected behavior. Try unplugging and replugging the device and check your Home Assistant ESPHome device list — it may already be connected and working.

Hold both the RST and Boot buttons simultaneously, then release RST while keeping Boot pressed. The Boot button must be held at startup for the device to enter Boot mode. Most computers handle this automatically during flashing, but occasionally manual intervention is needed. Step-by-step guide: docs.asc.com/bootmode.html

Yes. It integrates via ESPHome over Wi-Fi. Once flashed and added to your network, it shows up in your HA ESPHome devices and you can build automations directly from it.

No hub is required. For Home Assistant, it connects directly over Wi-Fi. For standalone use, the optional BLE wall socket add-on lets it work without any other hardware.

This typically happens because the inside of the mat is tight and needs to be loosened up. Rolling, bending, striking, tugging, and scrunching the mat can help loosen it and increase sensitivity. Mats generally get more sensitive over time as the top layer wears in. You can also try re-running calibration — press the calibrate button, apply pressure for 1-2 seconds, then release.

TrampleTek Blue uses a gradient-based algorithm that looks for quick changes in pressure rather than holding thresholds like SlumberTek. The sensitivity slider shows you how much pressure change is needed to trigger an on or off event. Calibration only requires a brief 1-2 second press, not the longer process used for SlumberTek.

Detection issues can happen if the mat has shifted position, if ambient conditions have changed significantly, or if calibration has drifted. First, check that the mat hasn't moved. Next, try re-running calibration. If you're on Home Assistant, there's a raw sensor data entity you can enable to see actual voltage values and help diagnose. Reach out to support@asc.com if you need help — we're also happy to schedule a video call.

If you're using the BLE wall socket, check the LED — it should be turning on and off as expected. If you're using Home Assistant (which has no LED indicator), check your HA history for connectivity status. The device may need to be recalibrated, or in the worst case reflashed. Reach out to support@asc.com if you're stuck.

Disconnects are usually Wi-Fi related. The ESP32 chip has a compact antenna and can struggle with range or interference, especially on the floor. Try: moving the mat to a spot with better Wi-Fi coverage, using a Wi-Fi extender or mesh node nearby, ensuring your router's 2.4GHz channel is set to a fixed channel, or making sure the electronics enclosure isn't buried under thick objects.

That's the factory QA firmware — the mat hasn't been flashed with Home Assistant firmware yet. Green means pressure is being applied; red means pressure is being removed. Run the firmware flasher to install the HA version.

TrampleTek Blue runs on a Wemos Lolin ESP32-C3 Mini, which provides both Wi-Fi and Bluetooth connectivity. The firmware is built on ESPHome.

Light surface cleaning is fine. Avoid submerging the electronics enclosure. We recommend spot cleaning only — do not machine wash.

SlumberTek is a discreet under-mattress pressure sensor designed to detect bed occupancy and movement. It sits between the mattress and the bed frame — no wearables, no cameras, no microphones. It connects via Wi-Fi to Home Assistant or the ASC mobile app and can send real-time alerts when someone enters or exits the bed.

SlumberTek was designed for two primary users: family caregivers monitoring an aging parent or loved one (bed exit alerts, fall risk awareness, long-distance peace of mind), and smart home enthusiasts who want to automate bedroom lighting, HVAC, and other devices based on sleep state. It's also useful for parents monitoring young children, post-surgery recovery, and overnight staff in assisted living.

It's a complement, not a replacement. SlumberTek doesn't see or hear anything — it only detects pressure. For infant safety especially, it should be used alongside other monitoring as appropriate. That said, it's excellent for alerting caregivers when a child or elder has gotten out of bed at night.

SlumberTek detects: when someone gets into bed, when they leave the bed, how long the bed has been empty, and nighttime movement patterns. It does not capture any audio or video, does not record identity, and requires nothing from the person being monitored.

SlumberTek is designed to reliably detect a single individual. If you need to monitor two people in the same bed, we recommend using two SlumberTeks — one per person.

SlumberTek detects bed exits — meaning it can alert you when the bed goes from occupied to unoccupied. Paired with a Home Assistant flow or the ASC app, you can set an alert if the bed remains empty for more than a specified time (e.g., 15 minutes) during overnight hours, which serves as a practical fall or wandering indicator.

Yes. Customers have used SlumberTek successfully on adjustable beds. We suggest using enough tape to secure the device and prevent it from shifting while the bed adjusts position. We recommend positioning it around mid-chest level for best detection.

SlumberTek connects to your Wi-Fi network. From there, it integrates with Home Assistant via ESPHome, or connects directly to the ASC mobile app. No hub is required.

Place the mat under the mattress and plug it into power via USB. Connect it to your Wi-Fi using the ASC app or ESPHome web flasher. Set your alert preferences. The device is invisible once installed — there's nothing to wear, charge, or remember.

Generally mid-chest or slightly below is ideal. Having the electronics enclosure near the edge of the bed (not buried in the center) gives better Wi-Fi signal and makes accessing the power cable easier. If your bed has slats, place a piece of cardboard, thin plywood, or rigid plastic over the slats before putting SlumberTek down — this creates a flat surface that can nearly double the signal quality.

Yes, but we strongly recommend placing a hard flat surface over the slats first — the packaging cardboard that comes with SlumberTek is perfect for this. Slats without a flat backing significantly reduce signal quality, which can hurt accuracy. With a solid surface underneath, slat beds work excellently.

Yes, and calibration matters. Every mattress and bed frame combination is different. The calibration process sets a baseline for your specific bed. Most users calibrate at initial setup and occasionally if they change their mattress or rearrange their bed. The device also has an auto-calibration system that adjusts itself over time based on your nightly data.

Absolutely — Home Assistant is the most powerful way to use SlumberTek. You can build automations like: turn on a nightlight when someone exits the bed, alert if no bed entry by a set time, log sleep and movement history, or integrate with other sensors for a full home awareness picture.

Not natively at this time. The primary integration pathways are Home Assistant and the ASC app. Via Home Assistant, you can bridge to Alexa or Google Home if needed.

SlumberTek is designed to be accurate 95% or more of the time under normal conditions. We're always making hardware and firmware improvements to meet and exceed that target. If you're consistently seeing accuracy below that level, reach out to support@asc.com and we'll help troubleshoot.

SlumberTek tries to strike a balance between being fast and responsive when you first get into bed, while also ignoring non-human weights like balled-up bedding or animals. That balance can sometimes lead to occasional false positives. If you're experiencing them regularly, reach out to support@asc.com — we can walk you through calibration adjustments. Our troubleshooting video at youtube.com/@AppliedSensorCo also covers this in detail.

The auto-calibration system can drift over extended periods when the bed is completely empty. If you return after a few days away and accuracy is off, a manual recalibration usually fixes it quickly. You can also increase the Auto-Calibration Trigger Sensitivity setting in the diagnostics to make the device more resilient to extended vacancies.

Check the 'Transition to On Delay' setting and make sure it's as low as possible — the default is 1 second, which is also the minimum. If detection is still feeling slow after confirming, see the troubleshooting section of our YouTube channel at youtube.com/@AppliedSensorCo for more options.

This is usually related to how the sensor signal recovers after you leave the bed. Check the 'Transition to Off Delay' setting and the sensitivity sliders in the diagnostics section. Our troubleshooting video has a dedicated chapter on fixing slow out-of-bed detection.

There's a dedicated section in our troubleshooting video on preventing pets from triggering SlumberTek. In general, adjusting the sensitivity threshold upward means the device requires more weight before registering occupancy — which can filter out lighter animals while still detecting people. Positioning the sensor toward the headboard side of the bed can also help, since pets tend to sleep toward the foot.

No. SlumberTek is always listening and reconnects automatically after Wi-Fi interruptions. You don't need to do anything to restart it after a power outage or internet drop.

The device reports a temperature value, but this is the CPU/board temperature, not ambient room temperature. Normal operating range is roughly 95–120°F depending on your mattress thickness and the device's position. It's primarily a debugging diagnostic and isn't intended to be used as a room thermometer.

Home Assistant will notify you within 6–12 hours when a new firmware version is available. You can update with a single button click from the HA interface — no USB cable needed for most updates. If you restart your device, it will check for updates immediately rather than waiting.

It depends on the update. Major version changes often require a recalibration because the algorithm or entity structure changes. Release notes will indicate if recalibration is needed. When in doubt, a quick recalibration doesn't hurt.

Probably not — this is a known intermittent issue with the web-based flasher. After Chrome relaunches, reconnect to the device and you should see the option to configure Wi-Fi credentials, which means the firmware installed successfully. If you're not sure, check the device version in Home Assistant under Settings > Devices.

Wi-Fi connectivity is the most common issue. The device uses a compact ESP32 antenna that can be affected by mattress materials and distance from your router. Try: positioning the electronics enclosure closer to the edge of the bed, using a dedicated 2.4GHz network with a fixed channel, or adding a nearby Wi-Fi extender or mesh node. Avoid having the electronics buried under thick foam layers if possible.

Yes. SlumberTek works well with mesh systems and dedicated 2.4GHz networks. If you're experiencing stability issues, setting a fixed IP address and fixed Wi-Fi channel can help. Using a separate SSID for your IoT devices (2.4GHz only) is also a common recommendation.

Yes — the ASC app is currently in development, with a target release of summer 2026. It will allow you to set up the device, view bed status in real time, configure alerts, and review activity history without needing Home Assistant. In the meantime, Home Assistant is the recommended integration path.

Yes, and it's one of our primary use cases. Because SlumberTek requires nothing from the person being monitored — no wearing a device, no pressing buttons — it's ideal for memory care situations. Alerts can fire based on bed presence and duration, giving caregivers timely, passive awareness.

SlumberTek can detect when a child gets out of bed and is a great low-friction way to get a nighttime alert if they wander. It should not be used as a primary infant safety device in place of a dedicated baby monitor — it doesn't detect breathing or fine movement within the bed. Particularly wiggly sleepers have been known to move to areas of the bed that the sensor doesn't cover, which can occasionally trigger a false exit alert.

As long as you have an internet connection, alerts from the ASC app can reach you anywhere in the world. Long-distance caregivers are a core use case — you can be in another city and still get a push notification if your parent's bed has been empty for 20 minutes at 2am.
