[shelly] New device#supplyVoltage channel for Shelly 2.5, 1PM and 1L

[elektro-joe]

Request

It would be great if you can add the item AC voltage to the Shelly Binding.

Possible Solution

On the web interface of the shelly device it's already available e.g.
http://192.168.xxx.yyy/status
(second to last key:value)

My Environment

OpenHab 3.0 on openhabian (Raspi4B)
Shelly binding v3.0.1
Shelly 2.5 Relay (SHSW-25) - firmware 1.9.4

[markus7017]

Why is that info relevant as a dynamic state (channel)? You know what you connected, this doesn't change dynamically.

I checked the API spec and it doesn't list this parameter for Shelly 2.5, but shelly_voltage for 1PM and 1L
Did you checked the current firmware and could confirm that the parameter is still there?

[markus7017]

I added new channel device#supplyVoltage

• Shelly 2.5: Returns measured value (status.voltage)
• Shelly 1PM/1L: Returns 110.0V/220.0V depending on settings.supply_voltage

try updated DEV build for 3.1M5
