This is probably such a noob question but I’m having trouble getting my Flipper to detect my garage opener. I open the Sub-GHz app and turned on the frequency analyzer. When I press the button on my garage opener it shows between 314-315MHz on the screen. So then I go to Read and choose 315MHz and scan while pressing the garage opener but nothing happens. I tried every optIon for Modulation too.
Am I missing something? It’s a Liftmaster garage opener in case you’re wondering.
Same issue here.
Same; my opener says 318mhz though. Not seeing anything even with the analyzer.
first, it uses rolling codes so you cannot capture and keep
second, there are a few users who are having issues with 125KHz and rolling back to .50 will fix that
Ok, even with rolling codes, strange that the flipper won’t even see it on the analyzer (for me at least). I guess it just can’t hit 318mhz?
they work exactly at 318.000? Can you take a photo of the nameplate on the keychain?
The brand is ‘Linear’, when I do a quick Google search for ‘linear garage door opener frequency’ 318mhz immediately pops up. It’s also stated on the opener itself.
I can confirm also I have a Linear model MT-1B with frequency 318 MHz listed on the back. My Flipper also does not pick up any signal on the analyzer. In the ‘Read’ section, what Modulation should I be set to?
Tomorrow you have to add this PR to the dev, you can update it, and then the analyzer will see 318 and will be able to record the RAW signal. also try to recognize the signal through Read, and if it doesn’t recognize it, please send me a RAW (AM) recording of 10+ clicks of each of the buttons, I will look at it and maybe add it to Read
After updating to newest dev firmware the analyzer now sees 318 coming in! Read still does not pick it up no matter the modulation I choose but it does sit at 318 when ‘hopping’ is turned on and I press the openers’ button. Recording the signal raw set to 318 comes in strong and exactly as expected, I am not near the gate this clicker works with to test it unfortunately… If you’re ok with a little hand holding I can try to get you the recording… I have it saved to my Flipper, now, how do I go about getting it to you? I’ve figured out how to save backups but haven’t gotten as far as pulling specific files for export yet…
if read does not see it, then the flipper simply does not know this protocol. send a photo of the remote control 2 sides FCC-id , and record raw 10+ clicks of each of the buttons. You can download it by simply inserting the SD into the card reader
Hi,
@SkorP - Just following up on this thread. I have the same issue with a MyQ / Chamberlain garage door opener. I’m on the latest firmware (0.50.0). It shows 314/315 in the analyzer but I’m not able to add it using ‘read’. Is this a known issue with LiftMaster products (LiftMaster owns Chamberlain - same/similar products).
this is NOT a problem, the flipper simply does not know this encoding, I do not have such a system in my hands, if you want flipper to support your systems, you first need to! ⚠️ My remote isn't supported | How to add new Sub-GHz protocol in Flipper Zero
linear’s mtr3 remote does work with the f0 in raw mode, including replay. 318.00 / AM270
and I think it’s the same for the mt-1b
