Errors generated by integration at HA system start-up

[SeeThisIsMe]

There seems to be a small coding oversight that is generating 2 errors with the integration at the start-up of HA.

There is a reference to “previous state” which I expect doesn’t exist at start-up, and therefore a couple of errors are generated only at start-up time by the integration. Errors are below:

Error 1:

Ahh yep. It was a change I did to fix water usage on the energy dashboard. Will fix and release today. Thanks for reporting!

[sh00t2kill]

Fixed in v0.4.7

Tested and looks good now. Thanks!
