Battery Temperature and Humidity Sensor THS-M1 Prototype

Battery Temperature and Humidity Sensor THS-M1 Prototype

With the help of Xiaomi Temperature and Humidity Meter 2, changing it to open source firmware, changing the CR2032 coin cell battery to be powered by a 7 cell battery, and then using the native BTHome protocol and changing it to a higher refresh rate, we now have a portable temperature and humidity meter.

Here's the prototype and we hope to share it soon.

Compared to the original Xiaomi Thermo-Hygrometer 2, it features:

• Direct access to HA via Bluetooth using open source firmware.
• According to new research on open source firmware, it can also access Z2M using Zigbee protocol.
• Higher refresh rate, response speed.
• Powered by a larger #7 battery to support longer-lasting use at high refresh rates.
• A 3D printed stand up stand, he can be placed anywhere.

Due to courier restrictions, even if we are able to share it, it will come without batteries.
