Home Assistant Wattsonic GEN3 MODBUS integration

Installation:

  1. edit configuration.yaml include packages according to minimal/complete installation, check my configuration.yaml

  2. copy wattsonic files all files copy to your config dir (where is configuration.yaml)

    a) minimal Wattsonic gen3 configuration start with this config. When your setup starts returning data, switch to latest configuration. minimal config has almost all sensors from modbus + 3 translated template sensor - copy just this older wattsonic.yaml

    b) my latest gen3 configuration - copy wattsonic_sql_postgre.yaml or wattsonic_sql_mariadb.yaml for sql sensors according to your db. Default HA is postgre - edit configuration.yaml and include corresponding db package - copy actual wattsonic.yaml

    this configuration consist of (but still does not has all registers):

    • almost all read modbus registers
    • switches for RW registers
    • can read Ecomode period 1,2 structure and has an example for writing structure
    • template sensors
      • Battery SOC ETA - time for charging/discharging battery
      • Grid Injection 15min - for Czech, grid injection in last 15minutes
      • Home Consumption Now and Today calculation
    • scripts for
      • setting economy/general/off grid mode
      • setting Grid Injection Power Limit Setting

    c) GEN2 configuration as GEN2 has differrent registers, you cannot use my wattsonic.yaml. but, Ivan has made this basic one wattsonic_gen2.yaml. enjoy and feel free to modify here on github

    d) Sunways GEN2 configuration from Martin Kremla - based on my latest gen3 config - source is here in sunways_gen2 directory

  3. edit modbus configuration in wattsonic.yaml default is connection over serial and RS485. Change port according to your RS485 module. if you are running over TCP/IP, just delete serial config and uncomment tcp config

  4. restart HASS

  5. edit your lovelace dashboard, you can take mine lovelace and just remove/use sensors - added sunsynk config
