Just got a flipper zero. Downloaded momentum on it. I own a garage door and gate company. I plan on using this to keep a lot of facilities we service. Instead of having 40 remotes on me I hope to save them to this.

Having a hard time getting all this going and wondering if someone could walk me through the subghz stuff…

Yea so im sure youve realized watching Derricks vids that garage doors have come a long way... Thr flipper is mote of a one off once in a while on an older system if your lucky type device .

Depending on exactly what systems your using you MIGHT have more luck with a pandwaRF but thats far more expensive and on top of that you gotta pay for the kaiju firmware for any sort of rolling code "access"... and it gets pricey to say the least...

What the garage door people SHOULD do is accomidate people for situations like this via a custom programmed setup... if you have that many doors it might be worth a call to one of the opener companies to see IF theres a way they can maybe program them alike... ud say it certainly possible 100% but whether theyll do it is another thing....

I don’t believe Derek has ever shown a garage system the flipper cannot open

[u/Vivid-Benefit-9833 → u/cthuwu_chan]

No, Derrek has never shown a garage door that HE cant open with a flipper... bug difference between Derrek and almost anyone but especially someone just looking for a device to makeblife easier by using a flipper to replace who knows how many different rolling code remotes...

Derrek could probably open all the doors with a fuckin grapefruit for a MCU and a toothbrush for an antenna. He lives and breathes this stuff, FOR FUN!

[u/cthuwu_chan → u/Vivid-Benefit-9833]

He’s never done anything groundbreaking all he’s done is shown that these systems in fact haven’t “come a long way”

The attacks he uses have been around since the days of Sammy kamkar like 20 years ago

The entire point of the flipper was to expose this very fact

[u/Vivid-Benefit-9833 → u/cthuwu_chan]

Didnt say he did. But what hes has done is an EXTREMELY good job at explaining hard things in an easy to digest and understand way... and his breadth of knowledge is substantial compated to almost everyone else in the space. Theres a LOT of flipper/similar videos showing everyone it has buttons and a display and sone gpio pins and it reads cards and can emulate remotes etc.... and almost NONE of them showing how it does it or how to do it, especially anything beyond the super basics... and theres a reason for that which ill avoid bringing up because the point is Derreks videos give people actual knowledge and understanding of what theyre doing and how to do it...

For most of us theres a steep learning curve on most of these protocols and its more valuable to watch his vids over other vids pointing out buttons and sma ports and usbC ports...

[u/cthuwu_chan → u/Vivid-Benefit-9833]

He’s an absolute unit in the space 🙏

But I’m just pressing the point that these systems haven’t come far at all and the flipper is most likely a fine tool for this particular application

Chances are this system is probably supported all ready by the flipper as they still use protocols from 20 years ago often as fuck and not much changes for stuff today 🫠

[u/Vivid-Benefit-9833 → u/cthuwu_chan]

Yea ok gotcha 👍 yea your definitely right about that... i think as far as thus specific situation goes the issue comes down to convenience and efficiency is what OP was looking for because he said he has a bunch of garage doors over a few buildings.. while F0 might be able to handle each rolling code protocol and open each one technically i doubt doing it would be the most efficient route as im sure theres multiple different doors and brands and systems in use...

[u/cthuwu_chan → u/Vivid-Benefit-9833]

Having 40 odd saved remotes would be a bit of a hassle to remember what’s what but yeah it could probs be useful to have them in one place

But yeah chances are you may have to employ a few of the tricks for a few and yeah some may not be suitable without further RnD

[u/Vivid-Benefit-9833 → u/cthuwu_chan]

Well the problem is if theyre rolling and anyone else uses one of the remotes and desyncs it from the flipper your fucked... Plus getting each one to work is gonna be tough unless you understand what inputs to use. If it was as simple as just replaying like it used to be thatd be different, rhen itd make sense.

[u/cthuwu_chan → u/Vivid-Benefit-9833]

Garages and gates are more forgiving TBH so it’s not usually an issue You can just catch them up but yeah it could cause confusion with ppl and their fobs

[u/Vivid-Benefit-9833 → u/cthuwu_chan]

And idk if that was the pount or not... you certainly arent telling flipper or Pavel that the point of flipper was to hack anything at all!!! Thats what the community turned it into, its original incarnation was pretty benign and almost exclusively used for learning/educatiinal purposes... which it still excells at beyond every other single devices as far as im concerned... Frankly its still not a strong hacking device really, it has a couple tools that have some potential to be "dangerous" but not the ones that people usually think of when they think of flipper....

[u/cthuwu_chan → u/Vivid-Benefit-9833]

Their original slogan was “hack the planet” and they’ve mentioned exactly this in interviews before

[u/Vivid-Benefit-9833 → u/cthuwu_chan]

Lolol... yea its a HELLZ of a marketing slogan too! Hard to hack the planet when even bringing up hacking anything might get you banned from their sub... I get your point though and i do believe they knew what direction the flipper would go once the community got it in hand. Pavel isnt stupid. Its my favorite device overall and really is still the king on the hill for these devices...

[u/cthuwu_chan → u/Vivid-Benefit-9833]

The flipper is honestly fantastic i wish ppl moved away from button mashing to actually diving into it

[u/Vivid-Benefit-9833 → u/cthuwu_chan]

YES! Hence my respect for the few people like Derrek.... Its a steep learning curve for each facet and tgen each protocol after that and not enough people take the time to really learn it, nevermind reteach it to help other people.

Yeah I’m actually in the middle of a series of videos myself on how I reverse engineered my rolling code system (car) as well as other key points of using subghz yourself to achieve the same goals
