Mixed data from T3 + ESP

Hi. I`ve connected to the T3 inverter according to manual "Foxess-T-series-ESPHome-Home-Assistant" by assembly12. I receive the data but it is somehow mixed up.
Some examples like on picture:
No 1 - this is way too high and by day it is decreasing
No 2 and 3 - those values are frequence but placed at current
No 4 - this is voltage for each line but I see it as W

What can the problem ?

I can't help you with the ESP integration, but i've linked you to another RS485 integrations wiki page - depending on your inverter the registers used change, the various protocols are listed here for different inverters https://github.com/nathanmarlor/foxess_ ... -Documents

Note that the T3 does not use modbus, and the information at that link is not relevant to it.

Yes, I know that.
I have noticed some improvment when I deleted few sensors from esphome yaml, which was`nt relevant for my T3 inverter, described as "#only relevant for models T8dual-T12dual and T15-T25)". Stilll I have error with total production which is now as T-Series PV4 Power in Watts.

Yep, I was replying to Dave.

There's an effort to get T series support without going the ESP32 route at https://github.com/LucasTor/FoxESS-T-series, but I'm not sure how far it got.
