Initially targeted at the Senec Home V2.1 System. In the Senec.Home system, only selected values can be changed by the adapter. Use of this functionality is at your own risk and must be activated manually in the configuration beforehand. Senec currently also no longer provides a reliable way to influence peak shaving via the web interface. For this purpose, mein-senec.de must be used. Whether other systems (e.g. V3) also work with it depends on whether they are also based on lala.cgi and provide the same JSON information. Even with integration into the Senec.Clound it is not guaranteed that the data can still be retrieved via the web interface (for this please report your experiences).

- Senec Home 4.0 / Blei
- Senec Home 6.0 Pb

- Senec Business V2 3ph / Lithium
- ADS Tec
- OEM LG
- Solarinvert Storage 10.0 / Blei
SENEC Systems that don't provide a local webinterface might be monitored by using the API functionality only. Please contact the developer if you have any input on this.

You can install the adapter via the ioBroker web interface.
- Open your ioBroker web interface in a browser (eg: 192.168.178.42:8081)
- Click on Tab "Adapters"
- Type "senec" in the filter
- Click on the "+" symbol of the senec adapter
In addition to the adapter installation you have to add an instance of the adapter.
- Open your ioBroker interface in a browser (eg: 192.168.178.42:8081) (if configuration dialogue was opened automatically after installation, skip to 4.).
- Navigate to Tab "Instances"
- Click on the wrench symbol of the senec adapter
- Now you can see the main settings of the adapter configuration page.
4.1 Type in the IP-address of your SENEC system (FQDN is also possible if you have a working local DNS).
4.2 You can change the polling interval, too. (Default: 10 seconds for high priority data, 60 minutes for low priority data)
Warning! If you are polling too often, your SENEC system will not be able to connect to the SENEC servers anymore! So please be aware of this!
4.3 If your network requires a higher timeout for requests sent to SENEC, please change the Request-Timeout in miliseconds accordingly. (Default: 5000 miliseconds)
4.4 In case there is an issue communicating with SENEC the adapter will retry several times. You can adjust how often it will try to read from SENEC. (Default: 10)
4.5 To space retries apart a bit more you can adjust the Polling Retry Factor. (Default: 2)
Example: Using default settings the 1st retry will happen 20 seconds after the initial try, the 2nd will happen 40 seconds after the 2nd try.
After each successful connect to SENEC, the number of retries is reset. - Click on Save & Close
Here you can find a description of the states (list is incomplete) and how to use them. All states of this adapter are read-only states.
-
info.connection
Data type Permission boolean R Read-only boolean which is true if the adapter is connected to the senec system.
This channel contains values polled from SENEC App-API.
-
MODULES_CONFIGURED
Data type Permission number R Read-only number, which represents the number of modules currently configured in the system.
-
MODULE_COUNT
Data type Permission number R Read-only number, which represents the number of modules currently known the system (incl. non-configured).
-
GUI_BAT_DATA_CURRENT
Data type Permission number R Read-only number, which represents the battery's current in Amps.
-
GUI_BAT_DATA_FUEL_CHARGE
Data type Permission number R Read-only number, which represents the current level of your battery system in %.
-
GUI_BAT_DATA_VOLTAGE
Data type Permission number R Read-only number, which represents the battery's current voltage in volt.
-
GUI_BAT_DATA_POWER
Data type Permission number R Read-only number, which represents how much power is coming from / going into the battery in Watts. Negative values are discharging.
-
GUI_BOOSTING_INFO
Data type Permission boolean R Read-only boolean, which we don't know the exact meaning of yet.
-
GUI_CHARGING_INFO
Data type Permission boolean R Read-only boolean, which represents if the battery is currently charging.
-
GUI_GRID_POW
Data type Permission number R Read-only number, which represents the power currenty coming from / going into the grid in Watts. Negative values are sending into the grid.
-
GUI_HOUSE_POW
Data type Permission number R Read-only number, which represents the power in Watts currently consumed by the house.
-
GUI_INVERTER_POWER
Data type Permission number R Read-only number, which represents the current power supplied by your PV system.
-
STAT_HOURS_OF_OPERATION
Data type Permission number R Read-only number, detailing the system's uptime in hours.
-
STAT_MAINT_REQUIRED
Data type Permission boolean R Read-only boolean, which represents if your senec system requires maintenance.
-

Data type Permission number R Read-only number, which represents the system's state.
-
STAT_STATE_Text
Data type Permission string R Read-only string, which represents the system's state in human readable format (sorry - we only have the german states from senec).

- Fixing issues with polling from senec api when token expires
- Old entries in changelog moved to old.

- Dependency updates
- Measurements for today and yesterday are also available by the hour
- Measurements for month and previous month are also available by day

- Unit calculation fixed if we don't know the unit yet per state_attr.js
- Added definitions for cascadeDevicesCount and mode
- Dependency update
- Migrated to i18n

- Dependency Updates
- Fixed: History rebuild will only run once now when requested (remember: To force rebuild you need to configure this in settings)
- Polling yearly measurements as year from API - not months (and summing them up)
- Added back AllTimeHistory with BATTERY_LEVEL_IN_PERCENT averaged and AUTARKY_IN_PERCENT calculated
- Removed selection to use https or http for lala.cgi. https is enforced now.
- reading all previous years (up to inception of SENEC) added again (to make this happen: activate recalculation of full history via settings)
- added today / yesterday again
- optimizations for measurements handling
- less log noise
- more silencing log messages
- housekeeping
- fixed datatype for WIZARD.SG_READY_CURR_MODE
- less logging (moved some info to debug again)
- Complete rewrite of the Senec API functionality. Thanks to @timfxtones for pointing me in the right direction
- No longer using the web-interface at mein-senec.de - it didn't work properly on the long run ...
- Still missing some datapoints so far. They will be implemented in the future.
- Updated to use new SENEC API via mein-senec.de - Thanks to @maett81
- Some code and dependency housekeeping
