My #smappee #energy #monitor (circa 2014/2015) recently died. It kept falling off wifi, and now I can't get it to broadcast its internal hotspot at all even when the blinking lights say it should be in pairing mode.
Cracked it open, can't see anything obviously burnt or otherwise, so I'll probably send it off to recycling and look into a more modern solution. Maybe #esphome and that six-channel expandable monitor to log individual circuits?
Have some #circuitboard photos. Looks ARM based?
