I have Venus OS running on a RPI and Guimods and RpiGpioSetup are installed there too
I have set up 2 outputs so that I can use them to switch 2 relay outputs on and off using temperature (Ruvvi).
The fan for my 2 MPPTs is also working.
I would like to do the same with my third MPPT.
How can I use the temperature to control a third relay that cools my third MPPT?
The logic for temperature alarms recognizes only the first two relays. That code would need to be modified. If I recall, Victron may have hinted they are considering modfying all relay use code to accommodate additional relays but don’t know the time frame.
For my part, I’m unfortunately have no time for any updates to GuiMods or my other packages at this time.
Hello Kevin
Ok thanks
Can I perhaps use a different Gipo and control it via Nodered for now?
I tried it but somehow the Gipo isn’t being read.
Is this due to RpiGiposetup…
Could be Venus OS takes over the GPIOs used for the relays. You could prevent that by taking the pin out of the /etc/veus/gpio_list. You can specify a custom file in RpiGPioSetup when running the setup script from the command line.
Gipo 3 and 4 are not used in the list
That’s why I don’t understand it!
