Zigbee Pressure Sensor for Smart Home 80 cm

Zigbee Pressure Sensor | Chair & Bed Sensor | 40cm & 80cm The Zigbee Pressure Sensor is an ultra-thin sensor strip that you can place invisibly under the cushion of a chair, sofa, or mattress. As soon as pressure is detected, a signal is sent to your Zigbee hub. This opens up a world of possibilities for smart automations: turn on the lights when you sit down, start your favorite playlist, or turn up the heat. The sensor runs on a replaceable CR2032 battery that lasts up to a year and is directly compatible with Home Assistant via Zigbee2MQTT and ZHA. It's available in 40cm and 80cm versions. Note: This is a binary sensor (detects pressure/no pressure) and not a weight sensor. A ZigBee hub or coordinator is required for use. Key Features Invisible presence detection Place the thin, flexible strip under a chair cushion, sofa cushion, or mattress. The sensor is completely invisible and reliably detects whether someone is sitting or lying down. Ideal for "smart chair" or "smart bed" projects. Direct Home Assistant integration The sensor is instantly recognized in Home Assistant via Zigbee 2MQTT (Z2M) and ZHA . No special converters or manual configuration are required. Simply pair the sensor, and it will appear as a contact or presence sensor, ready to use in your automations. Fast and reliable response Thanks to the Zigbee 3.0 protocol, the sensor responds instantly to changes in pressure. As soon as you sit down, the "on" status is activated; as soon as you stand up, it clears. Perfect for real-time automations without noticeable delay. Energy efficient and long battery life The sensor is powered by a single CR2032 coin cell battery (included). Thanks to the energy-efficient Tuya ZTU protocol, the battery lasts up to a year with normal use. Two sizes for every application The 40cm version is perfect for office chairs, armchairs, or specific seating areas on a sofa. The 80cm version is ideal for use under a mattress for presence detection in bed or across the width of a two-seater sofa.

"Good night" and "Good morning" scenes Place the 80cm sensor under your mattress.

Memories for the elderly Use the sensor to monitor whether a parent or person in need of care regularly gets up from their chair during the day. Receive a notification if no movement is detected for an extended period. Installation and Home Assistant Installation: Insert a CR2032 battery into the controller. Place the sensor strip in the desired location (e.g. under a chair cushion). Enable pairing mode on your Zigbee hub (e.g. Zigbee2MQTT or ZHA in Home Assistant). Press and hold the button on the sensor controller until the LED flashes. The sensor is automatically added in Home Assistant as a binary sensor. In Home Assistant: The sensor appears as a contact or presence sensor. Use its status ('on'/'off' or 'home'/'away') as a trigger in your automations. Plus points Invisible and effective presence detection Direct out-of-the-box support for Home Assistant (Z2M & ZHA) Fast and reliable response without delay Long battery life (up to 1 year) on a standard CR2032 battery Available in two sizes (40cm and 80cm) Affordable solution for creative automation Negative points Requires a Zigbee hub (cannot be used standalone) Binary sensor: does not measure weight or pressure levels CR2032 battery not always included as standard Sensitivity not adjustable (responds to approx. 3-4 kg) Frequently Asked Questions Does this sensor work with Home Assistant? Yes, the sensor is recognized directly and without any additional configuration by both Zigbee 2MQTT (Z2M) and the ZHA integration in Home Assistant. It's usually identified as a door sensor (model TS0203), but it functions perfectly as a push button sensor. Can I use this sensor to measure someone's weight? No, this is a binary sensor. It only detects whether there is pressure or not (on/off), but not the amount of pressure or weight. How
