Number to time

[kababoom]

Thank you for creating this repo. Nice clean way of communicating with the inverter, I like it...

Tried with a 8266 first, lights of the tll-rs485 were flashing but nothing received, also not with logging disabled (as per esphome wiki).

ESP32 WROOM 4Mb Devkit V1 working first try..

There's one thing that I don't like, it's the time value, but no matter what lambda I try or HA sensor I create I can't get it to any decent time format.

Currently using:

  - platform: modbus_controller
    use_write_multiple: true
    modbus_controller_id: ${modbus_controller_id}
    id: sun3p_Time_point_1
    name: "sun3p-Time point 1 start"
    min_value: 0
    max_value: 2400
    step: 100
    address: 148
    value_type: U_WORD

Did you change the RX/TX pin numbers when you tried the 8266?

[kababoom]

Yes, tried 1/3 and 13/15..

I've found that the 8266 is pretty picky on pin naming. For RX/TX I would use GPIO3/GPIO1 respectively.

The ESP32 is working fine so I leave it at that.

About the issue, I've created a few select entries with just the hours since this is the only thing I'm interested in..
