Bonsoir ! Depuis quelque temps j’ai une petite installation #HomeAssistant avec quelques appareils reliés soit en #bluetooth, soit via #zigbee, en appartement.
Je me demande si d’une façon ou d’une autre je ne pourrais pas couvrir la cave (2 étages en-dessous) et le garage (encore 1 étage en-dessous).
Je comprends qu’un ou 2 répéteurs comme l’AEOTEC ZI pourraient faire le job en Zigbee. Mais en existe-t-il qui font aussi Bluetooth ?
L’idée étant de connecter des appareils uniquement Bluetooth situés à la cave ou au garage à Home Assistant.
Une passerelle comme la NOUS E1 peut-elle être utilisée comme un relais pour cela ?
Merci de votre aide !

Let’s try in English…
For some time I have a #HomeAssistant network, with a few devices connected via #Bluetooth and via #Zigbee, in a flat (condo).
I was wondering if I could reach the « basement » ( 2 floors under) and the garage (1 floor under the basement).
I understand that 1 or 2 repeaters like AEOTEC Z1 might do the job via Zigbee. But what about bluetooth ? Do some repeaters allow to relay BT too ?
I’d like to connect some BT devices located in the garage and the basement to Home Assistant.
Can a bridge like NOUS E1 be used as a repeater for that?
Thanks for your help!

@YannnSud maybe LORA? I have the same question.

@iznogoud LORA would be a different network than my home network where my HA is, wouldn’t it? I guess it wouldn’t connect to HA.

@YannnSud have not gone through that rabbit hole yet. Early thoughts would be around lora receiver -> mqtt -> home assistant

@iznogoud you mean that devices connected anywhere (even like thousands of km away) can be reachable via MQTT ? Using some form of cloud I guess? (Yes I’m a total newbie and MQTT isn’t very clear for me yet)

Iznogoud 20h ago

@YannnSud no. The distance jump you would do it with lora. Mqtt is just how you would connect to home assistant if no native integration. The mqtt server could/would just be on the same machine as HA

@YannnSud for example:
1. movement sensor (your garage)
2. lora end point (your garage)
3. lora end point (your condo)
4. mqtt server (your condo)
5. HA server (your condo)

@iznogoud yes that could work… it works with a sort of central bridge, and distant devices?

Iznogoud 20h ago

@YannnSud yes. Again, this is hypothetical, the main thing to figure out is if two lora devices could communicate with each other in your setup. Everything else is just piping.

@iznogoud if I understand correctly, LoRa has a very, very large range, up to tens of km. We are talking about devices distant of a few tens of metres. But indoors, meaning several walls and floors to cross. I guess it would make it?

@YannnSud well, that is the part that I do not know / requires researching. Urban spots are less friendly to radio waves because of concrete, faraday cages, interference from other devices / networks and etc.

@iznogoud here they mention hundreds of meters of range inside buildings. I only need tens :)

Poor positioning of gateways & sensors leads to unstable connections and shortened battery life. This is how it works properly >>

@YannnSud then all systems are go 😎

@iznogoud :) I’ll try to gather more info about lora:)

@YannnSud there is also the response time: e.g. f you want an alarm, you should check the response times for your pipeline. And also forget cameras, lora is low bandwidth. Good luck with your tinkering!

@iznogoud thanks for your help!

@YannnSud welcome 😊
