Created a new topic for clarity from my earlier posts to see if anyone else can help?
Had similar problems to @stephendy and others. My fix was to delete the Meross Smartapp in ST Classic app, go back to ST new app and reinstall Meross sockets as per instructions. All appear in ST new app. Go to ST Classic --> Manage Favourites, activate the Meross devices - sorted. The trouble starts when you restart the Smartapp in Classic, so don’t. Otherwise the sockets work great - set timers in ST new app no problem. Control on/off from both apps and Meross app. Great product, great price
UPDATE - no longer working! The Meross app works fine on my two plugs but ST no longer controls them - if you click on the plug in ST Classic to switch on it shows the icon with a message “Turning On” and then doesn’t. I’ve deleted the Smartapp in Classic and reinstalled the plugs in ST new app and everything now works OK. Will update further …
PS just been having a read of some of the other posts here so see also @pavichokche for similar issues and potential fix.
