ESPHome and Liftmaster Security+ 2.0 *receiver*

Anyone aware of a Security+ 2.0 receiver for ESPHome?

I’m using two of these inexpensive 850LM receivers (about $27USD) connected to an ESP32/ESPHome with remotes that cost about $6USD each.

I can use the remotes at a pretty good distance to do whatever on the six different channels. Nice functionality for not much money.

Of course, what would be better for identifying individual remotes would be to have a receiver that passes the remote’s ID to home assistant to decide what to do with that specific remote. I could use and track a large number of remotes in that case.

There is the secplus project for decoding, but I’m only finding where it is used to control a garage door opener similar to the ratgdo project or the GRGDO1 device. But I’m looking more for something like ESPSomfy that listens to what the remotes transmit.

I assusme this has been done before, but not having luck searching today.

So did you try what you get out with basic 315 receiver (if anything)? I’m not familiar with this multi-frequency system, is it transmitting on all frequencies or just single selected one?

Good questions. Google AI, for better or worse, says:

LiftMaster Security+ 2.0 operates on 310MHz, 315MHz, and 390MHz frequencies simultaneously, a “Tri-Band” system that provides advanced security and long-range performance. Unlike older systems that used a single frequency, Security+ 2.0 uses a combination of these narrow-band frequencies for encrypted, rolling codes, making it more secure and compatible with a wider range of older and newer LiftMaster and Chamberlain openers.

I assume the remotes are transmit only, one-way pairing, which I assumed the receiver just remembers the remote’s ID and the rolling code. But, I’m in the dark as I don’t have a 315MHz receiver or an SDR.

The secplus github page does show recieving Security+ 2.0.

I’ve been waiting for an excuse to get an SDR.

What is the goal of this project?

individually identify the remote opening the garage?
simple open/close opertation of the garage?
Use this for purpose other than garage/gate?

Read it and still missed it. Have you considered Bluetooth?
How far range do you need?

Here’s one use case. We have a gate for our neighborhood. For little cost we could give contractors or our delivery drivers their own remote and have it work for a limited number days or hours during the day. (I’m doing that now with six channels.) It would be like a programmable keypad some systems provide, but no stopping to punch in the code and wondering if you need to add # or * after the code.

I’m finding the range is much better than wifi or z-wave LR, so could place a remote in an out building to control lighting (or whatever). Remotes are really inexpensive and come in their own compact package and a little clip, too.

Don’t always have to have a problem to solve first. :wink: I have a few extra battery z-wave buttons I haven’t found a use for — yet.

If you can receive the remote signal with common receiver, makes sense.
If not, whatever keyfobs and receiver could offer that functionality without too complex setup.
