Disable disconnected sensors instead of displaying theire last reported value


I have a few nodes that are disconnected sometimes (or some even un-removable(force) from the zwave network) these sensors keep their last reported value as actual reading which is very annoying and gives wrong data in the “energy” tab. or at the insight.homey.com

Lately I changed to an alternative DSMR reader and disabled the old one but don’t want to throw it away and lose all the data, Now the value is still accumulated in the energy tab as well, you can clearly see when i pulled the plug ( I disabled the grand total switch )

Actually, I don’t think the recorded data is removed when removing the device.
