Rheem Econet Wifi signal dBm not parsing correctly

@w1ll1am23 As my github was so nicely closed for the issue, the request was to place it in the forum. This is a bug as the value used to be a dBm. Unfortunately I cannot historically pull the value of when it exactly was broken as to fix another issue with the energy usage per day, I had removed the integration and re-added it deleting the historical data.

It looks like it was also discovered by someone else:

I wonder if this fixes it?
