Sensors sometimes unavailable

[oischinger]

Hi there.
First of all thanks for this great project. I was able to set this up quickly and I get all the relevant data into Home Assistant.
However I noticed that my energy Dashboard in Home Assistant goes crazy with the "Energy Provided" sensor. Even though the value barely changes HA sees a huge amount of energy returned to grid.
I noticed that the values are sometimes jumping to unavailable for a very short time. It seems to be when the data doesn't match the regex.
I fear this is what confuses HA

Is there a way to ignore those unavailable states?

Hi, unavailable values should not confuse HA. But if you get unavailable regularly you probably have a bad visual connection. This may cause erroneous readouts which definitely confuses HA.
I had a similar issue at the beginning and could solve it completely with the help of a 3D printed fixture which exactly positions my sensor in front of the LED.
