I have installed several Treatlife Smart Switches, set up in Smartlife App. I have created corresponding Virtual Switches in ST. In IFTTT I created two Applets - ST -> SL to turn on and turn off switch. IFTTT only allows one On Applet to control one switch and one Off Applet to control one switch. I don’t see any way to create more one-to-one connections for the rest of the switches. Retired IT and even I can’t figure this out.
Update: No way to do it using the IFTTT App, must create account on Website (will not let you login using user/pwd from App) then go to /create page to manually link ST to SL and set up all 4 trigger applets for each Virtual Switch.
