I’m working with Victron CerboGX, Multiplus-II and a Lifepo4-battery as part of my solar setup. I also have Homeassistant with Node-red installed, and now I want to enable one schedule, in the ESS “Scheduled charge levels" setting from node-red by Modbus, in Home Assistant (and not in Cerbo, Venus OS large) so I can charge the battery at cheapest hours in the night to a defined soc value.
Setup and communication work fine, but I can’t find the Modbus register value to enable/disable the ESS schedule anywhere.
I’ve also looked here: CCGX-Modbus-TCP-register-list-3.50.xlsx
Does anyone have this register value?
I can do a lot of workarounds, but the one I need suits me best, and I don’t want to hand control over to Dynamic ESS.
The next best thing would be enable/disable schedule by MQTT, but this leads me to the same dead end.
and then use the programm dbus-spy on venus-os to search for what you need. This is still not the register number, but an approch which will help for a node-red solution.
Hi Woob, From Jan 1 on I am going to run the same setup and looking for a solution to write via HomeAssistant into the scheduled battery registers. Did you find a solution already, Thanks Fred
It would have been the best solution I my case to control the scheduled charge in Victron by Home Assistant.
Plan B, is to send the individual commands from Node-red or Automation/Script in HA to Victron, as all the command are available in HA in the Victron integration.
But this also gives me concerns….like, what if the general network communication breaks down, while charging, or I forget and reboot HA while charging/communicating.
So doing it all from HA also means to considerate to have some actions to take care of “faults”
I’ve not done it yet (due to lack of time) and currently it works kinda ok for me to go with at static charge schedule at night. But hopefully within 1 month or two….
