Sonoff SV power through doorbell

Hello everyone! I’ve been fighting with this for a couple of days and decided to ask for help…
The sonoff sv works within a range of 5v to 24v with AC or DC, promising for dumb doorbells…
I cannot power it … Tried everything… Any clues?

I found it needs more than 500mA… does that help? I didn’t get it to work with 12v @400mA

That could be the issue! Thanks I’ll give it a try

Hi @loudmicro , I’ve the same set-up and thus same problem.

12v with 400mA doesn’t trigger the switch on the SV. What is a possible solution/workaround for this?
