There's lots of options there on the mppt itself , but I would like to be able to turn on/off the relays in mppts from cerbogx with a simple dbus command, just like the cerbo's relays. All I can find is a dbus state. Maybe in a future firmware update? or am I missing something?
Hi, I am searching for this option too. I want to use the relays on my mppts to control my cooling funs. I.e. when the temperature is too high (temperature sensor connected to the cerbogx), switch on the cooling fan. But i dont see the possibility to switch it on through the dbus
I tried this, but it seems it is not possible to control the relays in the MPPT through the dbus:
root@einstein:~# dbus -y com.victronenergy.solarcharger.socketcan_can0_vi1_uc216936 /Relay/0/State GetValue
value = 0
root@einstein:~# dbus -y com.victronenergy.solarcharger.socketcan_can0_vi1_uc216936 /Relay/0/State SetValue 1
retval = 0
root@einstein:~# dbus -y com.victronenergy.solarcharger.socketcan_can0_vi1_uc216936 /Relay/0/State GetValue
value = 0
Ok, I figured it out. You need to set the Relay mode to "Manual control" of the MPPT with the VictronConnect app, then you can do this:
root@einstein:~# dbus -y com.victronenergy.solarcharger.socketcan_can0_vi0_uc216898 /Relay/0/State GetValue
value = 1
root@einstein:~# dbus -y com.victronenergy.solarcharger.socketcan_can0_vi0_uc216898 /Relay/0/State SetValue %1
retval = 0
root@einstein:~# dbus -y com.victronenergy.solarcharger.socketcan_can0_vi0_uc216898 /Relay/0/State GetValue
value = 1
root@einstein:~# dbus -y com.victronenergy.solarcharger.socketcan_can0_vi0_uc216898 /Relay/0/State SetValue %0
retval = 0
root@einstein:~# dbus -y com.victronenergy.solarcharger.socketcan_can0_vi0_uc216898 /Relay/0/State GetValue
value = 0
root@einstein:~# dbus -y com.victronenergy.solarcharger.socketcan_can0_vi0_uc216898 /Relay/0/State SetValue %1
retval = 0
root@einstein:~# dbus -y com.victronenergy.solarcharger.socketcan_can0_vi0_uc216898 /Relay/0/State GetValue
value = 1
