Newbie wants to do everything wired
-
There's also a proposal to add PJON support: https://github.com/mysensors/MySensors/issues/1171
As far as I can tell @tekka has even created some code to that effect. More no that here: https://github.com/mysensors/MySensors/pull/1278

If you are thinking about RS485 system, have a look at my hardware:

I am also intresting in implementation of RS485 in my MySensors network, and i like yor hardware and use some of your ideas in my project Simple compact RS485 node (ATmega328 + MAX485) ,

Thanks for the proposal.
I have still one concern to use RS485:
My topology would be star topology, but RS485 is not designed for that.
Do someone have already experience with that?
Will it work with a lower baudrathe around 19,2k?
How big delay can I expect by using a motion detection sensor to switch on the lights? -

@tweaker
I'm also plan to use star topology, but still i build just one node :)
Use 9600 baud rate, and i don't have delay on my experience on this day.@cabat : Thanks for sharing. When do you plan to connect more nodes? How long will be the cables?
General Question: I saw as well the ESPhome.io which looks very nice for me. Is this something which can be combined with the mySensors protocol? I want to use NodeRed in the OrangePi Gateway to gather all the sensor values.

In fact now i have 2 nodes, but one of then only for testing purpose, sending temp every 15 seconds.
The cable is about 10-15 meters. -
@tweaker still not - not enough time to assemble additional nodes..
I have encountered problems that are still not clear to me when assembling the second board - it does not want to connect to the gateway.
I checked everything that is possible, but I haven’t found the reasons yet..
I will plan To assemble one more test node .. -
Star topology is not recommended to use with RS485, but it is not that it certainly won't work. You have to test it.
When it comes to experience, I have one with much more than 5 modules. It works pretty good, even if the modules are badly designed. To achieve top reliability though, you have to use well designed modules.

I know about it, but I hope that with a speed of 9600 and a small cable length it will work ..
