Ensure a sensors is updated after each read. #17

Closed jyavenard closed 3 years ago

jyavenard commented 3 years ago

The energy sensors based on an output (ending with _wh) may not contain the correct result due to how the iotawatt is calculating them (such as a typical Import and Export energy rule). It may be required to use the integration integration to calculate the energy the power device used over a given amount of time. For the integration to rule, the sensor state must be updated frequently. The Home Assistant value is to only update the value of a sensor if a change occurred which isn't what we want.

So we configure the HA DataUpdateCoordinator for forced updates.

Fixes #15

I assume you have made this change to your system. How is it working?

So far so good, now integration with the right method is correct.

Previously, the right integration would be over-reading by over 20%

Nice! Hopefully this gets accepted soon!
