Hi all
Just wonder if anyone knows the mqqt topic or modbus register to activate / deactivate a scheduled charge in ESS?
If there isn't one currently, with more and more smart electric tariffs coming on the market, it would be useful to be able to switch charging on / off with in ESS from an automation based on the current unit rate of electricity.
Thanks
Simon
You can use the custom node in node red and set the charging amps to 0 to disable inverter charging.
Hi Derrick
Thanks for the reply
Good point, that would disable charging, I will have to work around that idea.
I currently have a 4 hour cheap rate window where ESS Scheduled charge is active and the SOC is set according the the estimated solar for the next day. So set a low SOC and the inverter is basically idle and all loads are using cheap rate electricity.
I can't use a 24 hour scheduled charge because the battery would never discharge regardless of the set soc.
Ideally, the option to set a 24 hour ESS charge and turn it on and off from node red would be ideal as this would allow the batteries to discharge normally when on peak rate, but charge at off-peak rate and not allow discharging either
Not sure if just changing the charge rate would stop the batteries discharging during cheap rate but I will give it some thought.
Thanks again

Is this a Multiplus?
Maybe turning the Multiplus charger to inverter only with register 33 will do what you want.
1=Charger Only;2=Inverter Only;3=On;4=Off
