Project built based on an old D-Link router enclosure.

It is a Raspberry Pi 3 running Home Assistant with a RPi GPIO Gateway.

Dedicated power supply for the radio, wired through a 5v to 3.3v regulator from the 3A 5V power supply.
Ethernet and 2 USB ports available for connections.

No soldering.
Easy to build with some Hot Glue... took me 3 hours.

thanks @gohan I solved the problem by changing the power supply...

Now I'm powering through USB using a phone charger... so I'll never know if it was a soldering problem on VIN or a low current problem from the other disassembled phone charger... but it is working now...

Thanks for the help...

I had just cleaned it!!! My wife gave up caring about this desk...:smirk:

I found my multimeter fuse was burned... so I wired its base poles and now I can measure:

Sleeping + Reed Disconnected - most time 6 uA
Sleeping + Reed Connected - most time 9 uA
When sending new status to gateway - 25 - 230 uA (around 140 uA most times)
Sending time was less than 1 second.

2 AA will give me 29 years (battery certainly will die first)
2 AAA - 12 years.
1 CR2032 - 2,5 years.

Thanks for the help...
