Motion Sensor not presenting to RS485 Gateway / TSM:FPAR:NO REPLY
-
Hardware: Arduino nano boards+ RS485 devices with separate 5 volt power supply
I am trying to set up my 1st Rs485 gateway motion sensor on Home Assistant, per the following tutorial:
https://www.mysensors.org/build/rs485The motion sensor is not presenting itself to the gateway, so I did some digging and found this thread on the subject:
https://forum.mysensors.org/topic/11048/mqtt-ethernet-gateway-with-wired-rs485-network.
I have things wired up as per this pic provided in the tutorial
Although I am not using mqtt, everything seemed to be pertinent but I was still unable to get communication between the sensor and gateway.
Ha logs show the gateway seems to be happy:

@mrhutchinsonmn I haven’t used rs485 myself, but I think it will work better if you use the same speed for MY_RS485_BAUD_RATE on gateway and nodes.
-
@mrhutchinsonmn said in Motion Sensor not presenting to RS485 Gateway / TSM:FPAR:NO REPLY:
9600
Good catch.. That was an old version... both are set to 115200 after 9600 did not work
-
@mrhutchinsonmn Might have confused the issue with my reply.. Neither 115200 nor 9600 baud rates resolve the communication issue.
-
The sketch uses MY_RS485_HWSERIAL but you say you have wired according to https://forum.mysensors.org/topic/11048/mqtt-ethernet-gateway-with-wired-rs485-network which uses pins 8 and 9?
Pins 8 and 9 are not the hardware serial pins.
-
@mfalkvidd Ugh!!! Too many versions of the sketch :)... Had to switch between my laptop and pc because of sketch upload issues.... Must have grabbed an old sketch.. I HAD commented hwserial out earlier... Getting communication now but not a valid message, not enough values to unpack errors. I will dig into that tomorrow. Thank you!!!
-
@mrhutchinsonmn I would try 9600 again. 115200 leaves very little room for interference and oscillator differences.
-
Thank you for the advice!
I started over, just to be sure I didn't have anymore mix ups, but still have not been able to get the RS485 motion sensor and RS485 gateway to talk.

-
@mrhutchinsonmn At RS485, it's obligatory to assign NodeIDs within your sketch.
-
You should move the define for the node ID before you include mysensors.h
-
@rejoe2 In research, some stated it needed to be there if the sensor did not present itself. Followed @electrik advice and it now works. Thank you for your feedback!
-
@electrik Yes... that worked!!! Moved node and child id above mysensors.h
Thank you!!!!
