Sonoff Zigbee Temp/Humidity AA Power Mod

This mod transforms the Sonoff Zigbee Temperature & Humidity Sensor by replacing its original coin cell battery with a reliable rechargeable AA battery pack. A custom 3D-printed enclosure keeps everything neat, secure, and durable. I made this modification because the original coin cell batteries lasted about a month, and with these rechargeable AA batteries, I believe it will last much longer, making the sensor far more practical for long-term use.
