Transmitting an Alarm Signal with LoRa (600m)! || Improving my Garage Alarm System

[@LeoDDJ]

I would suggest adding a heartbeat feature to the code. So the transmitter always sends a "I'm still alive" packet every x seconds and when the receiver misses y amount of packets you know that the connection got broken

[@dauf69]

I like this idea. So simple yet quite important.

[@SlyerFox666]

One of the limitations of lora is An average of 30 seconds uplink time on air per day per device and at most 10 downlink msgs per day including acks for confirmed uplinks. Maybe different in other countries but that's the practical limitations we have run into using this tech. An not to mention the number of hacking articles out there which as far as I'm aware are untraceable using lora but I'm not an expert. 👍

[@GRBtutorials]

@@SlyerFox666 That's for LoRaWAN, not LoRa. You can use LoRa however you want, it's just a radio transmitting protocol. LoRaWAN is an international collaborative WAN (meaning it's not yours), which has a limited bandwidth, so they have to put restrictions in place.

[@tornadokat]

LeoDJ made a great suggestion about a heartbeat. Having designed a LoRa alarm system myself, I second that and add voltage monitoring into the message so you can detect if the battery is getting low for some reason. Also to avoid the risk of a single transmission failing thus not triggering the alarm, I would like to suggest having the transmitter keep sending the alarm message until the receiver sends a message back that says "Hey I got your alarm message" and the transmitter then stops re-sending the message.

Not really, he just sends the same code multiple times, checksum won't fix anything here it will only make the receiver aware of corrupt data. The receiver already does this where if the received data is not the alarm trigger code, the data is corrupt... In a more complex system you would absolutely want checksum or even ecc features but here it wouldn't serve a purpose.

The hub sounds like a cool secondary system you can add to improve it. First, using a SMS service, you could configure your system when it receives an alarm signal to notify your phone. This way, even if you're not at home, you still can be notified, and plus, that doubles as a time-stamping data logger, since you can look at your phones timestamp on the SMS for record.

[@arnaud7671]

I'm not sure about the 100m rule. It's probably a power limitation, not a distance limitation. Because with the right antenna you can totally connect to a vanilla WiFi network more than 100m away. And it work the same with LoRa , 433MHz hardware, or any other frequency. As long as the emitter respect the rated EIRP for the used frequency, you can improve the range by improving the sensitivity of the receiver.

Now he has a $300 alarm system with only a few basic features. Best buck for your bang! Though he probably paid only a small amount, as the expensive parts (mainly the Controllino, which is not exactly adequate for the purpose, it's like using a bazooka to kill a mosquito, but I guess he had no other use for it) were given to him for free, not to mention that even just the ad revenue of a single video most likely gives him more than enough to cover it.

[@emmanuelr6698]

Interesting, as always ! A bit of explanation could be added : LoRa is like the low side layer of OSI (close to hardware stuff) and LoRaWAN is an application layer that can link you to the Internet (providing a service). I saw that there is at least one free LoRaWAN service (The things network). So, you could actually link your alarm to the Internet through a close enough gateway. If there is no such gateway, then you might use the provided gateway and create a LoRaWAN node. That can explain why you were given the gateway.

[@raspberrypicodeiteatit6903]

Good video, and i do like to add something you didn't mention. the restrictions when using LoRa, the configurations you mentioned in the video and you skipped them because they was kinda complicated, they exist not only to improve the transmission, but also to set up the limits which depends on the law (roles) set by the government. so you need to watch out from that, can't wait to see the upgraded version of this project, keep up the good work

[@MrBrelindm]

I would've started with the antenna system. Since you have just one garage and one home it makes sense to utilize a beam forming antenna system between the two. This is an easy way to comply with legal maximum broadcast power requirements. Assuming the radio frequencies involved are in the 900Mhz band, the size of the required antennas is acceptably small and would not run afoul of HOA rules or other local regulations. High gain antennas with tight beam patterns raise the effective radiated power without breaching broadcast power requirements. I once rebuilt an 11 element left hand circular polarized antenna for the 2 meter amateur band. It had a gain of 22dbm and a beam divergence of 7°. I used it to talk with stations all up and down the eastern seaboard from southeastern Michigan on just 2 watts of power! I had started out using 12 watts input but had to dial it back after my next door neighbor knocked on my door to tell me that he and his wife could hear my side of my conversations through their television's speakers, and they weren't even watching television at the time!

I'd suggest to add a message signing function, like crc, to avoid most of the errors. I read some comments about a hearbeat periodical message, i'd recommend using a hashing + salt protocol like salted SHA256. A thief could just do a replay attack and deactivate the alarm. Car keyfobs use a "rolling code" to avoid replay attacks, but i don't think it would be easy or useful in your application, better use hashing + salt. Cheers, and great video as always ;)
