DIY Zigbee outlet sensor
Based on a battery powered sensor and a battery replacements
Introduction
Zigbee sensors, like a temperature sensor measure periodic the current temperature and run on a battery for a long time, but still that battery needs to be replaced from time to time.
Sometimes you just want a solution which always works, without the need to replace batteries once in a while.
This solution works for all these types of sensors:

My solution
You can create a DIY WiFi based temperature sensor with the BME280 temperature sensor and a 5V adapter powered ESP, flashed with ESPHome.
Or, what I choose, use a Zigbee temperature sensor and replace the normal battery with a dummy battery adapter to USB and connect it to an outlet.
There are multiple battery-eliminators:
- For AA batteries
- For AAA batteries
- For a CR 2032 cell battery
Required hardware
This project only requires these devices: A battery powered sensor and a battery replacement kit with a power adapter.
I have a Zigbee network, so I use a Zigbee temperature sensors, but any other protocol sensor can also do the trick.
Combination 1: Temperature sensor with CR2032 battery replacement
-
The Aqara WSDCGQ11LM is a CR2032 battery powered temperature sensor
Combination 2: Temperature sensor with AAA battery replacement
Combination 3: Leak sensor with AAA battery replacement
- It also works with other sensors like this leak sensor with two AAA batteries. Zigbee leak sensor (AliExpress) (Amazon)
Combination 4: motion sensor with AAA battery replacement
-
It also works with other sensors like this motion sensor with two AAA batteries.
Any other solutions or feedback? Please let me know!
