Strange behaviour with mysensors + RFLink

[Fabien]

It's probabley a request to find parent (t=07)

@Fabien

Thanks for feedback,

I'm not an expert, I just want to know if is it normal behavior to have packets send by mysensors lib in empty project ?

Thanks for your clarification

@knop maybe it is your neighbour node? or a node you forgot somewhere? :D

[knop]

Good remark :-)

But I've checked this point ;-), I've disconnected one wire of my NRF24L01 and no more packets received on RFLink ;-)

[Fabien]

@knop With an empty sketch, you have some packets from node to find parent (gateway).

Hi,
Little update. So I need as you said a serial gateway. The question is : does rflink is equivalent to mysensors gateway ?
If not i need to build a serial gw and connect it on usb port of my raspberry and declare it on domoticz interface. If yes how to configure domoticz to manage rflink + others protocol ? (Declare 2 gateways (rflink and traditionnal gw) on same usb port?
Thanks for your help.

@knop
RFLink is not equivalent to a MySensors gw, and won't be. You should better use a MySensors gw.
Else i would wish them good luck to handle the full Mysensors lib (and updates), plus some others protocol, without loosing packets etc..

I don't use a RFLink, but what I'm pretty sure is, actually, :

• it can only receive MySensors nodes, as RFLink is sort of sniffer. It can't be a part of the MySensors network, with id etc, so it can't send commands to MySensors nodes.
• If MySensors encryption is enabled, or also signing, then it would become even more difficult for the RFLink to listen something (its basic task)
• especially, because RFLink doesn't use MySensors GW code. Make sense it just sniff/listen.

When using a MySensors GW, you can also benefit:

• sending commands of course
• the full MySensors protocol and features
• MySensors library updates
• controllers (like domoticz etc.) have dedicated plugins for using MySensors, which make this even more friendly to use compared to a generic sniffer (because the plugin is customized for MySensors features)

I'm pretty sure there are others relevant point, but I hope this clarifies :)

And with RFLink, you can only use 2.4GHz frequency. It doesn't work with RFM69.
Actually I have a MySensors Gateway and a RFLink (not for the same usage)

Ok thanks you guys, I will try to make a Serial GW with Arduino Uno + NRF24L01
And to connect this GW to my Raspberry Pi3.
But I very disappointed about RFLink, and do not understand why there is an option "MySensors" on it !

Thanks again for clarifications.

You can connect nrf24 directly on the rpi, there is no need for the UNO
