myPV
Home Assistant Component for myPV
Installation
HACS (recommended)
Add user defined repository 'https://github.com/dneprojects/mypv' for type integration. Search for integration 'myPV', use the three dot menu on the right side to download. Restart Home Assistant. Add integration 'myPV' in the settings
Manual download
Copy this folder to 'config/custom_components/mypv'. Restart Home Assistant. Add integration 'myPV' in the settings section.
Configuration
The integration is configurated via UI. Enter an IP address, at which a myPV devices will be found.
Features
The myPV custom integration works locally in the home network utilizing the http api. So it doesn't need any login.
- The integration is written to support multiple devices. However, it is only tested just with one (ELWA 2). For multiple devices, please use the configuration step with a different IP address.
- It offers binary sensors and sensors for all data points provided by the myPV devices.
- The heating power can be set manually by an input number between 0 and 3000 W (3600 W for ELWA 2, 9000 W for AC THOR 9s). This will turn on the heater for a predefined time period. This period has to been setup via web or cloud setup, as it is not supported by the myPV api. However, if the power value (usually the surplus of collected solar power) is set by an automation repeatedly within that period, a continuous control can be achieved.
- In the same way, an upper power bound for the device's internal PID controller can be given. The internal PID controller uses the same time period as the external control described above.
- In order to enable both control entities, the control type has to be set to "html" via web or cloud setup. Otherwise, only sensor data points will be exposed as Home Assistant entities.
Credits
This integration is based on an implementation https://github.com/zaubererty/homeassistant-mvpv. Although it worked fine, the main feature, controlling the device by home assistant automations was not possible. So I totally rewrote the integration. However, thanks to the work of zaubererty at this place!
