Several of my KP115 units were recently presented with a firmware upgrade to 1.1.1 (from 1.0.21) and now SENSE shows them as offline and no data is coming from them.  I removed the TPLink integration, renabled it and it only found my non-KP115 v1.1.1 plugs.

A majority of my home uses these plugs to monitor various power usuage, and they are now bricks in terms of using Sense to collectivly monitor my power usage (of course they still report correctly in the KASA app)
