Senec Home Binding

Binding to request status information from Senec Home Batteries to allow home automation decisions based on your current energy management.

If your power feed is limited by regulations for example, you can switch on devices if a limited rate was applied by your Senec Home device. In addition you can switch off devices if the power consumption is getting higher.

Examples: Lights, pool filters, wash machines, ...

Supported Things

Thing type id	Name
senechome	Senec Home Lithium Battery, V2.0, V2.1, V3 and V3duo

Note: Not all channels are available for all Senec Home types. E.g.

• only V3, V3duo have a power generator and thus MPPs (V3 has 2 MPP, V3duo has 3 MPP)
• not equipped battery packs will return 0 for all ...Pack channels
• currently channels for the first wallbox are implemented (senec could handle 4 wallboxes)
• Senec disables http access at ~30.08.2023

Thing Configuration

demo.things

Thing senechome:senechome:pvbattery [ hostname="192.168.0.128", refreshInterval=60, limitationTresholdValue=70, limitationDuration=60, useHttp=false ]

If the thing goes online then the connection to the web interface is successful. In case it is offline you should see an error message. The refresh interval is 15 seconds by default, but you can optionally provide your own value adding the refreshInterval key.

The property limitationTresholdValue is used as threshold for channel powerLimitationState. It is combined with property limitationDuration (seconds) to define a stable status for power limitation. Therefor use powerLimitationState to trigger Events (switches) based on your current power limitation.
