A note about shutting down the device
Flexit recommends that the function to turn off the unit is not made accessible in the interface for an ordinary user. It will therefore be removed from the integration in the future.
The consequences of shutting down the unit can be costly and extensive. For example, there can be condensation issues in freezing temperatures, and rotary heat exchangers can freeze.
If you need to shut down the unit, make sure to take all necessary precautions, such as securing the system with frost protection dampers.
Furthermore, Flexit recommends unplugging the unit from the power socket before replacing a filter. To prevent damage, always initiate a controlled shutdown from the control panel (or, in the future, from an action in Home Assistant) before unplugging the device.
Data updates
The integration pollsData polling is the process of querying a device or service at regular intervals to check for updates or retrieve data. By defining a custom polling interval, you can control how frequently your system checks for new data, which can help optimize performance and reduce unnecessary network traffic. [Learn more] data from the Flexit device every 60 seconds by default. This interval is not configurable.
