Humanity Sensor

[rain inlet]

I currently have a KNX in-wall temperature sensor, but it doesn't work very well. I experience several-hour delays or simply incorrect data.

Is there a good sensor, or combination of sensors, for motion, temperature, and humidity that works wirelessly over Matter, Zigbee, or Wi-Fi? It should be small, battery-powered or rechargeable (lasting at least a year on a single charge), and not require a power plug.

you could try wiring together an ESP32-H2 with some sensors

if you design the PCB and components yourself, you could save energy on that

but you would need like a LiPo battery or something if you want it to last a while
