Using multiple frequencies
-
Hi,
There's something I did not understand in how a Mysensors network should be organised : how can we use various frequencies depending on sensors ?
For instance, I built my gateway by installing a NRF24 on my raspberry PI (already used for Domoticz) and I have several sensors using also NRF24.
Now, I'd like to add LoRa radio to handle some sensors which are a bit too far: should I create a second gateway (ethernet gateway for instance on standalone arduino) with the Lora radio, and this second gateway would also be integrated in Domoticz ?
Or should I create a new sensor with repeater capabilities, attached to my current NRF24 gateway, meaning the new repeater sensor should have both NRF24 and Lora modules ?br,

You could use either option.
a new gw might be the easiest to do... but you could add a promini with the lora on it an have a 2 wire serial link to a second promini and have that one send data back to the exisiting gw. Either way you are looking at 2 more arduino boards.
Is the distance too far for nrf repeater with pa/lna modules and directional antenna?

Hi,
Thank you for your replies.
@skywatch : I'm not sure to understand the setup and the configuration. If you know where it would be explained, I'd appreciate a link with technical explanations (HW+SW setup).My target is not to avoid HW at all costs, but more select the easiest & most stabme approach.. If I must purchase 1 or 2 minis or even a raspberry, it's not end of the world (but a mini is more "envionment friendly than a raspberry which consumes more power, I think).
My main purpose would be to install a garage door sensor on ground -2 of my building while I leave on +7.. so 9 concrete floors in between..I think it's difficult with traditional NRF24, but I admit that I did not try.
Another usage (well, if the other works, that one is more for fun ), I would install a similar sensor in another garage door which is at approx 500m from my building in -1 flor of another buildin (with a couple other in between) : for that one, it would be to see "if loar really works far away" ;-)
One of my worries is that Lora does not seem to be well documented on this forum/website. I did post a couple questions several days ago, but despite it seems feasible in Mysensors, I got no answer, so I'm aware I might face heavy difficulties.

My thoughts were to do as follows.....
In the garage have a sensor>pro-mini>lora to send signal long distance.
Then more locally have lora>pro-mini>serial data out to sedond pro-mini2.
Then from second pro-mini2 serial data in>pro-mini2>nrf24l01+>gateway.So 2 x pro-mini with a serial connection back-to-back as a relay.
But now you have described the application in much more detail I would be tempted to just add a lora gw as it's less bother.
