Bridge between RF24 and RS485

[Yveaux]

@gohan You can have as many gateways as you like, as long as these form separate networks.
A single controller can connect to many gateways (networks).

[gohan]

That's what I meant 😀

@dk_iot I have been playing with the same idea but then realised that using repeaters should be ok as well.
'What are you issues with repeaters' could be a more interesting question because I get the feeling that you are trying to give the patient some medicine without really knowing what to cure...
Or am I wrong?

Its possible both ways - yes, but with a repeater you would not have to specify your network and the "healing" process which is one of the nice features in mysensors would work for a node in range of both repaters. This would not work with two different networks/gw.

@marceltrapman
One of the problems I had that the auto healing of the network started to loop/route into each other. So packets never arrived to the Gateway. The other one was a female NRF connector attached to a female antenna connector (took some time before I figured out). My current solution is one USB Gateway, and only one repeater, and two BIG antennas (with a male-to-male cable) between them...
I am hardcoding Node-ID's and Parents ID's now in my scripts.
What I am really missing is a way to define/set the parent ID in my script (Arduino Sketch), it would mean that I can have a single script for all my nodes, and configure the next hop (parent ID) before starting the NRF radio.
Do you know if this exists?

A repeater feature would be amasing. I posted a feature request on github, but i think it is better here:

I would like to build a wired network with RS-485 based sensors, because wireless signals can't go through the location where the sensors are. But outside of the metal house i can send and receive messages via NRF24L01.

So but the current MySensor library supports only a LAN, WLAN or serial gateway, but i need a NRF gateway. ;-)
Because there is no LAN or WLAN available. Would it possible to do this?
I think two ways could be useful:

1. a real gateway function
2. only pass through between RS-485 and NRF without an extra gateway

Which one would be easier to implement? I could help with this, but i don't exactly know the best point to start at. Allows the current library structure this modification?

[ArduiSens]

This would be a great step forward because today I can't find a good solution for connecting a RS485 wired sensor network to my Synology NAS without using USB (USB is complicated when using Arduino boards)

By option 1, do you mean a gateway-interface device like translating RS485 data into Ethernet?

I can do some integration testing :wink:

[gohan]

Rs485 gateway exists already in mysensors

[ArduiSens]

I know but not with the interface RS485 to Ethernet or NRF24L01+.
Only RS485 to USB which doesn't work when connecting to Synology NAS, in this case you also should wire it up to your NAS.

[hugch]

@ArduiSens No i mean not a ethernet gateway. I mean a gateway between RS485 and the wireless network.
Currently there exists only a gateway from RS485 to UART but not to the wireless network.

[gohan]

@ArduiSens actually it should be working with all gateway types
