This mod transforms the Sonoff Zigbee Button by replacing its original battery with a reliable rechargeable AA pack. With a custom 3D-printed enclosure, everything stays neat and durable. I made this modification because the original battery lasted about a month, whereas with the rechargeable AA batteries, I believe it will last much longer.

This is the link to the Zigbee button so you can purchase it from E-BAY

You will also need two M3 heat-set threaded inserts.
