💬 Building a wired RS485 sensor network
-
in the 2.2 the same problem, i have now updagradet to alpha.
When you have a solution on 2.2 i will downgrade. no problem!
Guys you are good! I had set the mynodeid. But befor i include the my sensors.. that's the mistake..
hour of hour to search... thx!

I just trying to work with examples but my node always transmitting some piece of shit from hardware serial:

I have tried also with RS485 with different baudrate. Finally I just connect my USB TTL directly to ouput pins, but always same result.
How to fix it? -
@Pavel-Polititsky
To me this looks like you mixed between-node communication (RS485) with debug output (and maybe also serial output of the gw).
The corresponding serial interface for RS485 should be dedicated to RS485 exclusively. -
Hi,
first of I have to thank you for your effort on this project! It helped me a lot.
In my house I would like to build 2 networks, one with serial gateway with RF24 for ground floor and outside. Second will be in cellar and I was thinking about Ethernet gateway (W5500) but sensors will be connected via RS485. Do you have code for that? On the video it looks like that in the box on right side it is something like this. -

@giebek could you describe the problem, what your setup looks like, and what you have tried so far to troubleshoot it? There are 137 posts in this thread so it is a bit hard to figure out which problem you are referring to.

Imo this indicates your node doesn't have a NodeID yet. When using RS485 you have to assign the ID's manually in the sketch, auto doesn't work... (e.g. #define MY_NODE_ID 123)

hello MySensors friends,
I am currently making a node based on an arduino Mega 2560 with transport via RS-485, the build page says that we should use the MEGA pin 46 & 48, I was wondering if I would like a reference for this. in the sketch.
Second question; can I use pin 47 for the DE pin with:#define MY_RS485_DE_PIN 47I haven't tested anything yet, so actually I just ask a lazy question ;)
-
Hello, I would like to better understand the concept here. It sounds like we still need a gateway connected to a controller (serial, Ethernet, WiFi, etc.) but the interface between gateway and multiple nodes is over wired RS485 serial interface. Please confirm. Thank you for your great efforts!

@apl2017 Yes, also for RS485 variant you'll need a gateway. Only the communication between the gateway and the other nodes is handled over RS485, connected to a second (typically software) serial interface (for remote nodes, you may just use the hardware serial interface to connect the RS485 transceiver, if you do not need debug output; but imo this option is not recommended for beginners).

I have it working, so you don't have to adjust anything for a Mega, and pin 47 for DE also works!

I have a node with 52 child id's on a Arduino mega,
Arnout 22 of Them receiving data (relay & dimmers) and the rest are sending data, binary, temp/hum, soil moisture and analog data.
Not all the nodes are in use, but i see the data in domoticz.
I dont know how manny childs you want to use, for me 52 on one node are very mutch.
