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:
temperature:
- offset: -2
- round: 2
humidity:
- round: 3
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. Sensor filters are working for temperature and humidity values only for now.
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
