Integration for SEC1000S (Smart Energy Controller)

[Dodo7308]

Hello,
Have you considered create an integration for SEC1000S (Smart Energy Controller) ?
If so, I will provide you with the data I have obtained so far.
SEC1000S provides summary data for all connected inverters (consumption, elektrometer, etc.) and it also automatically balances the export limit to the network between inverters.
If you communicate directly with the inverters and set the power limit for export for any of them, SEC1000S automatically overwrites this power limit every second (via RS485). This means that the export limit can only be set on SEC1000S, not on the inverters.
I have mapped several packets, I can already read data and write the power limit, and other parameters, I already know which byte/bit means what, the only thing I have not been able to find out so far is the CRC algorythm.
I'm currently reading data from SEC1000S without CRC checking and I can aslo write the power limit "hardly" (0kW and 10kW) (I set this limit via the ProMate application and captured packets for power 0 and 10kW, which I also send to SEC1000S with CRC, which is fixed).
I have tried about 30 different types of CRC, but I have not succeeded yet.
If someone has a CRC for SEC1000S, it would be great and appreciated if can provide it.
What about the SEC1000S integration ? Can you do it?
