We’ve had a lot of fun with the THS-M45 units, which come with BTHome firmware and are ready to use straight out of the box. Now, after testing them for a while, we’re sharing this ultra-high-precision temperature and humidity sensor with Zigbee firmware, and we hope you enjoy using it.

A few notes:
- The firmware uses ppvx’s ZigbeeTLC.
- Press and hold the side button for more than 10 seconds to reset the Zigbee settings.
- Z2M offers better support; we recommend using a Z2M environment.
- The overall signal strength appears to be slightly better than that of the THS-G4.
- The battery level display appears to be inaccurate; it rarely shows 100%. This may be because the motherboard uses a separate LDO, and the current measurement voltage is inconsistent.
- We usually attach a label to the back of each device, which contains the device’s MAC address and the device name used in Z2M, to make it easier to identify.
- If time permits, we will include a desktop stand so that it can be placed directly on your desk.

Accuracy Improvements (Typical)

Relative Humidity (RH):
    •    SHT40: ~±1.8 % RH typical
    •    SHT45: ~±1.0 % RH typical (better precision)  

Temperature (T):
    •    SHT40: ~±0.2 °C typical
    •    SHT45: ~±0.1 °C typical (twice as precise)
