@Kevin_Z 

Thanks for the reply but this is not I wanted or meant.  For the older TP-Link HS100 or HS110 (which I have a total of 5 of them), the HS1x0 powers up the appliance it is connected to once it is attached to the power socket on the wall, so in instances where there is a power failure of the house and once it is recovered, the appliances automatically powered up again without me needed to remotely using KASA to tell the HS1x0 to power it up.  This does not seem to be the same for this newer TAPO P100, the applicance does not recovered from a power loss.

@MikeSee I can confirm this that the Tapo plugs will need to be manually turned on after a power failure. Disappointed upon learning this myself after buying and using the Tapo P100 and P105. I guess I might have to try those Kasa plugs. I wish there is a way to interconnect the two smart plugs product models (Tapo & Kasa) in one single app and seamlessly be able to control them within. That way, maybe an upgraded Smart Actions feature (similar to what's in the Tapo App but with IFTTT-level of control) of a particular Kasa plug that has recovered from a power failure can be used to automatically turn on those low grade Tapo smart plugs.
