Will the Aladdin built into the 3053 also monitor/operate the Stealth 750? I just bought both and had read that Aladdin will communicate with three openers.
The model 3053-TKV with the Aladdin Connect built in, will not operate another garage door opener that does not have Aladdin Connect built in. The Aladdin Connect Retro Fit Kit can be added onto any garage door opener, and with extra door position sensors, can be added on up to three. So you could use the 3053 as is, but you would have to add the Aladdin Connect RetroFit Kit to the Stealth 750 to get them to both work through the Aladdin Connect app.
Where the light bulbs are there is a red light what does that mean
Normally that means you do not have the Aladdin Connect setup complete.
