I know it is possible to turn the generator ON / OFF via the API. The documentation does not show how to set the run time. Is there are a parameter or D-bus path for that?

Is it possible to set generator run time via API or MQTT?
Hi! I’d like to help and give you the answer, but don’t know by heart and I’m not near a computer either.
However, I can help a bit in the right direction: to find out if there is such path (on dbus, and then automatically also on mqtt), configure your relay for generator start/stop and then login to ssh and run dbus-spy. You’ll see all available paths.
Alternatively; read through the source code of generator start/stop:
https://github.com/victronenergy/dbus_generator
If you do find such path; please help me and add it to the dbus wiki page:
https://github.com/victronenergy/venus/wiki/dbus#generator
Thanks for the guidance @mvader. Ben seems to have discovered the path we need. Now looking for the REST API equivalent.
BTW looking at dbus_generator.py we noticed that "batterymeasurement" is defined twice under "settingsbase", which could be a bug (or a bug waiting to happen).
The D-Bus path you want is com.victronenergy.generator.startstop0/Generator0/ManualStartTimer. The unit is seconds. Write this value first, and then write ManualStart to 1.
Thank you Ben!
Do you know if that is also accessible via the REST API? I know the gen start is available.
