Thank you for being part of the SlumberTek early access open beta!
Together, I hope we can improve the accuracy of bed presence sensing for home automation enthusiasts like yourself and possibly expand into medical or security applications in the future!
Install Firmware
Go to https://docs.asc.com for the latest installation instructions. You will receive Home Assistant notifications whenever I release firmware updates. Information about the Home Assistant UI elements can also be found at the link above.

Install SlumberTek
Place your SlumberTek sensor under your mattress at chest level, with the electronics box positioned toward the outside edge of the bed, which helps keep the WiFi antenna clear of the bed frame and reduces strain on the USB-C connection.

Here is a side view showing the recommended placement of the SlumberTek electronics case for both slatted and box spring beds.

Tips for Slatted Beds
If your "Pressure Voltage" signal in Home Assistant shows very little difference between in-bed and out-of-bed" (<0.05V), try the following:
- Ensure the sensor covers as many slats as possible.
- If 1 doesn’t help, try placing a piece of cardboard or thin plywood under the sensor to increase contact area and improve signal strength.
- Avoid positioning the sensor over just one slat, as this reduces contact area and signal accuracy.
That's it. You're Done!
