sensor 'error':'no data' after latest update

[Housebeer]

Behavior:
After the latest update my meter_readings sensors are not responding. Smartplugs are working, current consumption is also working so it seems like there is an issue between the library and the custom component. I'm reading through the code of both but haven't found the issue.

System:
Rpi with Hassbian Image
Home assistant version: 66.1 (latest)

Possible Solution:
?

Looks like there's no powerUsage key returned from the API? @costastf your the expert on that part, what do you think?

I saw the error in my original post is related to the Gas_today sensor, funny enough the gas_today sensor does report the correct value. Meter_reading sensors do not report correctly, so here is an error related to a failing sensor:

#33
i don't know what happened but compared with a previous code and just saw the entities were gone.

[Costas]

Yeah, we removed them thinking that they are not used on the last commit. Thanks!

[Housebeer]

Fixed in the last #33 merge! Thanks a lot. Issue can be closed if it was up to me.

@costastf I think it is a fun statistic since the daily electricity sensor doesn't tell you if you used it in "dal tarief". With this sensors you could reveal this.
