Wifi'ing the Heltec balancer.

Frankenstein mode engaged! That's a Sonoff SV Wifi switch configured in isolated dry contact mode, powered from the B- B+ via a 24V regulator.

I think it needs a fuse as it's going to be directly connected across the battery. It could be doing with being tidier!

For what it's worth. No, this did not go into service. Instead I bought a DC powered Wifi Smart swtich from Tuya for the purpose.
