Web page says that there are only 2 products which support Energy Monitoring - P210M (wall plate) and KP125MP2 (plugs).
But it is not correct, as there is at least one more unlisted plug with energy monitoring - P110M.

Very hard to find out what supports what...

Question: Is there any outdoor plug with energy monitoring supported? 
From the look at the model naming, the last letter 'M' could be for 'Monitoring'?
Then - Tapo P400M - does it have energy monitoring? 
Thanks!
