Hi,
problem there is no communication in master slave mode according to the documentation monitoring protocol point 2.3.2.1. The inverter on the latest software on port 1-2 rs485 sends 3 different frames with 30 second intervals
Frame 1 (Heartbeat)
Frame 2 (Device Attribute Information)
Frame 3 (Real-time Information)
So every 90 seconds you can read data from the same frame The inverter sends information every 90 seconds
Generally, apart from reading, by design I need to send a command to
register 51801 ActivePowerLimited
value and read the group 14,000 (on request with a higher frequency)
Hardware-wise the bus works.
I try to change the software to 1.20 (as I read on the forum) -not help.
Service does not respond to reporting the problem.
Anyone solved a similar problem?
Is there another way to read and change inverter settings via an external device?

I'm sorry to say that the T series does not support modbus / RS485 to be able to send commands to, only polled sensor data is provided.

This is an old thread (before the T series exposed RS485 on its comms pins), but explains the problem https://github.com/assembly12/Foxess-T- ... /issues/14

Thanks for the answer.
Can it be replaced (external control, change settings )by api or other methods?

I'm not sure whether this helps, there is an option within the OpenAPI to set the ExportLimit although I don't know whether this applies to all inverters or only Hybrids.

Setting the ExportLimit would reduce the inverters output and it is easy enough to test, the Energy Stats app uses the OpenAPI and provides the ability to set the ExportLimit in Settings, Inverter, Export Limit.

If that does what you want you would have the option of coding it using the OpenAPI to make a settings change .
