I do have LED lights (both in the opener and in the ceiling), they have been installed for years without any issue.
I moved the Meross to be about 8 inches above the Craftsman opener, no issues now, can easily open from the end of the driveway. I had previously installed the meross directly on top of the Craftsman.
Still have the weirdness with the wall control turning off when using the Meross. Redid the wiring and it didn't fix the issue. Not a huge deal for me, just resets the clock when I use it.
For those wanting to use it with Google Home/Assistant, add by linking the Smart MeRoss and create a custom routine like "When I say "open the garage door'", have Google "Ask Smart Meross to open the garage door".
