Hi! Recently try connect ESP32 with Sumry SP 7000 by using ESPHome Pip solar, without any success. Invertor just never reply.
But by using Solar2Mqtt i was able to connect and communicate with Sumry.
The main issue was Lib battery mode, for so,e reason it blocks communication by rs232. After switch to USE Solar2Mqtt was eble to handshake with Sumry and indicate PI30 protocol.
Is anybody was able to reach communication with ESPHo,e project to sumry devices? Cause Solar2Mqtt wasn't suitable for my future expend of data logging.
Trying to get as much as possible info, before starting to port Solar2Mqtt code of handhsace and protoc processing to ESPHome
