EDIT: Edited for Venus v3.0x. See below
A frequent requested feature of mine (and others on forums discussing off gird systems) is a means to turn on or off the MultiPlus with a switch. With a stand-alone Multiplus you can connect an external switch but when the Multiplus is connected to a CCGX or VGX the external switch does not work and you have to dig deep into the remote console to turn the Multiplus on/off.
I have created a service that monitors a digital input and when it goes from high to low it turns the Multiplus ON if is is OFF and OFF if it is ON.
I had to create a new digital input type: #12, "Inverter control".
Below is a link to the python service repository. Patches for the gui-files and dbus-digitalinputs service can be found in the "diffs" folder. Under releases there are prebuilt installers for Venus GX and Raspberry PI.
For those of you that want to build it, here is the Bitbake recipe with instructions:
Use at your own risk!
