LiftMaster 8355W AC Motor Garage Door Opener

Make: LiftMaster
Model: 8355W
How identified: Sense Identification

Additional Comments: Have 3 openers that are all the same model. Sense sees them as all the same . Opening and closing waveforms are pretty much the same as well. I should point out that Sense does not see the 7W Always On for each opener.

Power Specs: 120VAC, 60 Hz Voltage, 6A Current Rating, 1/2 HP AC motor, 7W when on standby

Update - adding HS110 view plus switched all 3 to LiftMaster 8550W
I was replacing some garage fluorescents with LED panels today (80W to 42W) and had the chance to put my HS110 on a couple of my garage doors that had formerly been detected by Sense. 2 revelations:

  • Sense is only detecting the closing/down activation for 2 of the openers. Can’t check the third right now. Sense used to see the up cycle and down cycle of all three as just one when I did the original posting.
  • The HS110 also reveals the garage light cycle. I have 2 LED bulbs in each opener, so 20W. Once the bulbs go off, standby is now 2W vs. 7W with my previous openers.

Looks like the Sense model has improved and native detections for my 8550Ws are now tracking the Travelling HS110 again.
