I’m about to automate my garage door and I’m debating between the two implementations.
I have an older opener that would require a MyQ add-on (888LM) / Internet gateway (828LM), so price-wise, the total cost of connecting the door would be the same as LFM-20 with SmartSense Multi.
With recent community driven integration of MyQ, what is the recommended way to connect garage doors?
IMHO, I would go with the LFM-20 because it will work with most all garage door openers. You mention yours is an older opener so I personally wouldn’t invest in something specific to it since it may need replacing some day.
I actually chose to go with the Linear FS20Z-1 versus the LFM-20. It is a little cheaper and it works great.
I have only had mine installed for a month now and I haven’t had any situations with it descending on its own. Honestly I see this relay no different than the standard doorbell opener button or car openers where the garage could close while someone is walking through. That is why I have the sensors installed to stop it from descending if someone is walking through.
IMO, the biggest thing to verify is that your garage door opener just has on/off on the wires coming in. If so, the LFM-20 is easy. Mine was a Genie opener with Intellicode which encodes multiple buttons and lights into the same wires. You can’t just wire up the LFM-20 easily. I soldered the LFM-20 to a remote control that I’d taken apart using some videos I’d seen online as reference. Not a convenient solution and I would have happily used an add-on to the garage door opener if one was available.
My opener has only 2 wires coming out of it and a control panel is attached to it. It’s not a simple door bell button, it has motion sensor, temperature display and a bunch of other controls.
I gotta look into it, but I don’t think I could wire up the LFM-20 easily. Getting another remote control to hack into would not be cost effective. LFM+Tilt+Remote > MyQ.
