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 |
| Socomec E23 Energy Meter 3-Phase | socomec_e23 |
| Socomec E03 Energy Meter 1-Phase | socomec_e03 |
| r4dcb08 Temperature Dallas Board | r4dcb08 |
| CWT-TH0x Temperature and Humidity sensor | cwt |
| SHT20 Temperature and Humidity sensor | sht20 |
| Liquid depth sensor | liquid-sensor |
| Orno-or-we-517 Energy Meter | orno-or-we-517 |
Example config¶
modbus:
uart: uart4
modbus_sensors:
- id: sofar1
model: sofar
address: 1
- id: sdm1
model: sdm630
address: 32
- id: Liquid sensor
model: liquid-sensor
address: 41
- id: CWT TH0x
model: cwt
address: 61
- id: SHT20
model: sht20
address: 62
sensors_filters:

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.
- sensors_filters (Optional, dictionary) - dictionary of
sensor_name: list of filters. See example above how to use those. Currently possible filters are for temperature and humidity. For filter list see Filters
Footnotes¶
-
Those energy metters can be found in two versions and only one supports Modbus - sometimes it’s marked with suffix
M(SDM120M/SDM6301M), other timeModbusis mentioned in the title. Don’t confuse it with cheaper version with suffixD(SDM120D/SDM6301D) - it doesn’t support Modbus communication so it can’t be connected with Bone.io. ↩ ↩2
