Dynamic Export Surplus Power

[imneofit]

Hi,

Has anyone created a function that will dynamically change the value for "DeyeInverter Export Surplus Power"?

For example I am interested that this function to constantly monitor the "DeyeInverter Grid L1 Voltage" and when the Voltage hits 252V or more, to drop the "DeyeInverter Export Surplus Power" by 15%.

At the same time, the same function to increase "DeyeInverter Export Surplus Power" by 15% if "DeyeInverter Grid L1 Voltage" hits 248V or below.

Hi,
I'm looking for this feature too.

I'm currently changing the Dynamic Export Surplus Power Value using two simple automations. I'm sure you can do it too.

Perhaps better control can be achieved with the HACS PID Controller integration with Home Assistant?

Another question: Since the firmware update, this value can be set up to 24,000 watts. Unfortunately, the integration only accepts 15,600 watts. Can this be adjusted?

Have a nice Sunday!

Yeah, thanks for your feedback. I ended up using two functions as well but I'm now hitting another wall.

Ask ChatGPT where to hardcode that value.

I integrated the inverter directly using the IP address of logger/inverter wireless adapter. It seems that I can read/write once every 5 seconds. A lot can happen in 5 seconds and I'm not very happy with this limitation. Are you using a different RS485 to read / write every one second perhaps?

ChatGPT is a good idea; it also suggests https://github.com/soloam/ha-pid-controller.

Read the values ​​directly via Modbus. Perhaps this will result in shorter readout intervals.

Hi @tomikCH, thanks for your update, here is fix: Export Surplus Power range in Deye
