SUMMARY

It would be a great benefit, if there where a "signal strength" plugin (like the battery plugin) - just to check the state of the device mobile network. I could also be included to the battery plugin (and name it like "stat plugin").

Why this is useful? Same reason, why the battery plugin is useful. Just one situation: if you have bad mobile signal at your location, you would put your phone at a place, where it's possible to receive calls and SMS (maybe outdoor or near a window). Then using kdeconnect is a pretty cool solution, because you will receive notifications (calls, sms, etc.), when the phone is somewhere else. But you never know, if you have currently a mobile signal - so, if you are waiting for a call, you have always check the signal on the phone itself.

So, i think, this would be a very handy feature - just get the signal strength and provide it on the kdeconnect protocol.
Thanks!
