Ok thanks. I will have a play but may do the same thing. It is a shame as the manipulation required is nominal and it would be nice and simple. Jeremy

@MartinViljoen did you manage to find a way to post the system mode settings whilst respecting whatever combination the api needs and the length of the helper ?

Having installed this yesterday 1. Just look in entities and you will find them all. You don't need to do anything. 2 there is no need to install the card but it does look nice. my issue is writing changes to the system which I think it a little picky ( the Sunsynk end ) and hopefully someone will share their method

As a minor update by.adding the curly brackets I got the battery capacity to change. other settings which I have tried in various combinations return the errors

Firstly thank you - I now have the invert information in Home Assistant. Did you ever find a way to update settings that was compliant with the length of a helper? I have tried a few things below all with error 500 - the inverter serial has been edited. If there are a set number of parameters that needs to be sent do you know the minimum set ? If the minimum set exceeds the HA text limit did you fine a work around ? I just need to decide if I top up batteries on a cheap tariff on Time period 3 and 5 or not. So I would be ether setting those parameters to charge or not based on the battery state of charge. So enable Time 2 and Change the SOC2 to 100 to charge or Disable Time 2 and set SOC2 to 10 to continue discharge Thank you Updating Helper: input_text.solarsynk_x_inverter_settings with: "cap1": "80", "cap2": "80", "cap3": "80", "cap4": "80", "cap5": "80", "cap6": "80" { "code": 500, "msg": "Internal Server Error", "data": null, "success": false } Clearing previously set temporary settings.
