Simple commands insteon integration on Apple watch

Even since I added SimpleCommands to my new Apple Watch, when I turn on/off light using physical light switch, it reverted to the previous state after a short moment. The only way to turn on/off the light and have it stay that way is to do it from the Watch. Can someone help me with this problem? If it continues, I’ll have no choice but to remove simple commands because I can’t have the light switch not working. Karen
