CozyLife Smart

My smart plug is crashing after last update. Worked wonderfully well before the update. Now it works only a few times & then says no connection. I then reinstall it & it does the same thing. I also have 2 of the wifi thermometers & they still work perfectly. Hoping this problem with the plug can be fixed because I really like using these items in my greenhouse & if im away i can check temp in the app & if to hot i could turn on the fan plugged into the smart plug from anywhere.

I have been using this app for many years now and it worked fine with the smart sockets that I purchased. Now I would like to add more smart devices to it but am unsure what devices are compatible. The smart sockets were of no particular brand and when I looked them up to find more information about them and who makes them it led me to a dead end. I was curious what could be connected to this app like speakers and cameras or just switches and lights? Otherwise good simple interface and good options to interact with. The automation is precise and useful.
