Modbus sensors

Dependency modules

modbus

Modbus sensors component. You need to know address of device you want to connect to! Supported devices:

Device	Model name
Eastron SDM6301 Energy meter	sdm630
Eastron SDM1201 Energy meter	sdm120
Sofar Solar PV Inverter	sofar

Example config

Example config

modbus:
  uart: uart1

modbus_sensors:
  - id: sofar1
    model: sofar
    address: 1
  - id: sdm1
    model: sdm630
    address: 32

Configuration variables:

• id (Required, string) - uniquely identifies this device in MQTT and Home Assistant
• address (Required, string) - modbus address of the device you want to communicate with.
• model (Required, string) - model schema to use. Check table above to get model name.
• update_interval (Optional, timeperiod, default: 60 seconds) - update interval. Modbus connection is pretty cpu intensive so customize with care. Minimum is 1 second, but recommended minimum is 10 secs.

1. Those energy metters can be found in two versions and only one supports Modbus - sometimes it's marked with suffix M (SDM120M / SDM6301M), other time Modbus is mentioned in the title. Don't confuse it with cheaper version with suffix D (SDM120D / SDM6301D) - it doesn't support Modbus communication so it can't be connected with Bone.io.↩
