It’s been a while since I have posted anything. Als lost my previous account.
I wandered if there was a possibility to have a timed run on relay 2 as there is on relay 1 for the generator. I live off grid with my victron install and I have a warm water boiler hanging on my relay 2 switch. But in sometimes I forget to switch it off and then it keeps using power. It would be easy if there was a way to keep it timed running and that the switch would turn off automaticaly
thanks and keep up the good work
You can do this with Node-RED using the large Venus OS version. A relay in manual operating mode can also be controlled by Node-RED. You should be able to note the time when it turns on and then turn it off after a set interval. With Version 3.60 of Venus OS (currently in beta testing) you can create extra Virtual Switches that could also be used for this sort of switching.
I am almost sure in node-red you can read the relais state using the relais input node without any “virtual switches”. Write a simple fuction to detect a false to true rising edge and use a delay node to switch that relais back off using the relais control output node. Quite easy if you are a coder. If you aren’t it might be a good 1st step into the node-red environment.
