HI. I Have some big problem. I have a Deye solar Inverter, and got af code for uising i HA.
I got esp32 to TTL and from TTL to modbus in Deye solar inverter.
It worked for 1 day, and now i got some problem. Cant see if it is hardware problem or problem with other things in HA.

This here is Yellow.
ESP32 Is offline in HA but in the logs it is online, and i can read the logs with wifi.
We have no clue what you’re talking about until you post your ESPHome code (in formatted text, not screenshot)
I googled the inverter and find this
StephanJoubert/home_assistant_solarman: Home Assistant component for Solarman collectors used with a variety of inverters. (github.com)
how do i do that?
You get this error, if there is an error on the modbus.
Which hardware do you use for the ttl to rs485 (link?)
I recommend this one, as it only needs 3V3 and no control_pin
RS485 naar RX-TX TTL 3.3V 5V omvormer module SP3485 (domoticx.nl)
i use esp32 to ttl and from ttl to deye inverter with cat 5 cable.
Funktioniert es mittlerweile ?
did you fix this? i have same problem but with sofar inverter 
So it looks like there are different methods, at least I’m now aware of 4 methods, 3 of which I’ve already been able to test myself, although I like the methods with a LAN connection the most. 1) Solarman ntegration and with mqtt. 2) Esphome unfortunately my wifi keeps dropping out even though the router is only 2 meters away. 3) The Sunsynk https://www.youtube.com/watch?v=u9df0YHfNtM&lc=UgyMBEmbr7f61DSt7F54AaABAg.9yEdfPD3aU59yGoaEV0iao 4) With a Waveshare. I haven’t tested it myself yet, it works under ioBroker and with a little skill it shouldn’t be a problem with HA.
