hello
Does Shelly Plus 2PM work with 12VDC (as supply voltage and control voltage)?
Wanted to use it to open/close valve that is controlled via 12VDC

A Shelly plus 2PM is working with 12V DC supply, but has to be modified. This thread gives a glimpse in the guts of the Shelly and has a sketch of the internal power supply:
How a modification can be done is described here with a Shelly 2.5 which is very similar to a Shelly plus 2PM:
Please be aware that voltage, current and power measurements a not working with DC supply. And the two relay contacts are bound to GND.
hello
thanks for answers
so without soldering it will not work if I connect instead of 24VDC just 12VDC?
Indeed, it will not work with 12V DC without modification. But with 24V DC, it will work out of the shelf. Without power measurements, as described above. Plus 24V is connected at pin N, GND/minus at pin L…
thanks
I will maybe use 2 potential free relays to switch 12VDC and power them with normal 230VAC. Then need to add normal Shutter Controller in between and it should work.
Can I use Shelly mini with 12VDC on relay side and with 230VAC as Supply Voltage? Will this work?
