So I like Zigbee sensors but hate the idea of having track & change batteries.
So I’m thinking off getting some Zigbee dev boards, connect sensors to them, power them with USB wall warts, and some sort of 3D printer enclosure.
So here are my questions:
What sort of firmware is out the for me to flash it with?
Can I use any sort of chip? I mean, the Sonoff style USB dongles are super cheap on AliExpress and have GPIO holes I could connect your avenged Temp/Humidity sensor to right?
