SolarCharger MPPT Relay

Hallo,


when will the feature to control the relay manualy be offered?

I'd like to use it to turn fans via Homeassistant on and off, but from victrons FAQ you can read that it will be developed in th future (since 2022).


https://www.victronenergy.com/live/venus-os:large#controlling_relays

/Relay/0/State    <- Read to see the state of the relay in the Battery Monitor. In case configured
                     to the "Remote" mode, using the VictronConnect App [SEE NOTE], the relay can be controlled
                     by writing to this path.
                     More information also here: https://www.victronenergy.com/live/venus-os:large#controlling_relays

                     NOTE: currently, 2022-08-17, VictronConnect does not yet offer that settings. It is
                     planned for later in 2022. Until then, the relay control in the MPPT cannot be set to this mode by
MPPT SmartSolarRelay

I already created switches in Homeassistant which send 0 and 1 via MQTT.

From MQTT Explorer i can see the state changing from 0 to 1 and viceversa, but the relay on the MPPT does nothing, als you cant select the remote function in the victron connect app.

Thanks for the Bluetooth and Firmware updates.

Now it's possible to control the relay from the Connect app, but still no response via MQTT and HA.

So i can see the state switching in MQTT explorer when I use the app to open and close the relay, but still no reaction when switching in HA, except state changing in MQTT explorer.

@Groove

I think you will find there is never a timeline given.

And probably this is on a back burner, there are some bigger features being worked on like DESS and the new GUI.

Also please read the community guidlines. It specifically mentions asking when xyz will be released....

A shelly switch might be a cheap alternative for you. Can be turned on via node red http nodes. Or MQTT
