Sensor reading incorrect data from the controller

Brian Fernando last edited by
I have OpenHAB on Rpi as the controller (serial) and few sensors. All the sensors require simplex communication work perfectly. But my (only one) relay is not responding at all. When I switch it On, I get 'ffffff' and when Off, it's '000000'.

Testing with MYSController works fine.

I'm using Arduino IDE ver 1.6.7 and MySensors ver 1.5.4. Please help. Thank you.

Serial output below.
```
read: 0-0-3 s=1,c=1,t=2,pt=0,l=6,sg=0:ffffff
Incoming change for sensor:1, New status: 0
read: 0-0-3 s=1,c=1,t=2,pt=0,l=6,sg=0:000000

The updates have been applied to Rev 2, below we have a list of everything that has been added/modified; Modification footprint for 3 items to make it easier to mount (Slow blow fuse, Thermal Fuse and Voltage Regulator) when hand soldering. Modification to nRF24L01+ Module to remove the short to ground on VCC line. Added the additional silkscreen labeling that was missed off by accident. This should be all that is needed for Rev 2 to be a successor to the Rev 1. We still have the issue with having to use pogo pins to program through the ISP connection, or to temporarily solder jumper wire into the 6 pin connection while uploading, then everything else can be programmed through the on-board FTDI connection. Will get the gerber files generated ASAP and then get them sent off for testing production runs.

Good to know, indeed my setup is working now with stable libraries thanks to this helpful community. I'll go back later to development libraries to see if I'm able to work with it as well.

Hi and welcome to the MySensors community @augusthalverson ! In general, you just set the color in your controller. It works the same way regardless of which type of gateway you are using, so there is nothing specific about mqtt. You might be able to get some inspiration from https://forum.mysensors.org/topic/4934/wall-mounted-mood-light-v2

That's cool, just thought I would throw it into the pot. I don't use OpenHAB so can't be of much help there i'm afraid.

By creating the file org.eclipse.smarthome.mqttbroker.cfg in the service folder (/usr/local/etc/openhab2/services in my case, chown to openhab), with the contents name=mosquitto host=192.168.1.69 secure=false port=1883 username= password= retain=true I was able to just create the MySensors MQTT gateway (using paperui) and it stayed online (no mqtt broker defined, but its addon is installed). I had the impressions that with the latest versions it should be possible to do everything in the PaperUI, and that the broker would use the mqtt2 addon (but in paper ui, service, config, mqtt tab, mqtt system broker connection, manage->plus button -> expert mode, I get to see the contents of the cfg file above) But unfortunately, it seems that the discovery services enters a endless loop (maybe I need to update my arduinos sketch to the latest mysensors code?) and I don't get any auto discovered things. If I trigger a new discovery it will stop the previous one and start again. Finally, I was able to manually create a thing, and link items on it. Eventually my battery level and humidity were displayed in the paper ui control page (after some weird delay, not updating once it shows in the log. the temperature didn't show up though). Not sure if my understanding is off (or paperui is limited in this sense) but in the "thing" creation page I only get to specify one child id. Then my multi sensors/value nodes would need to be define in multiple things? As I can't properly define channels for each child id, and I'm not sure what var1-5 are all about. I'll try defining things/channels/items directly in files in the following days, because so far I couldn't enjoy most of the benefits of this new version (auto discovery, logical grouping of physical device in "things", questionable "do-it-all in paper ui"), and I'm almost considering using mqtt1 binding in the new install

@micah said in Can't get OpenHAB2 to see my MQTT messages: I'm still not sure if the second and third line in the mqtt-eventbus.cfg is correct. I don't have MyMQTT anywhere else, so I think I may try different combinations to see what works. MyMQTT should be replaced with brokername (mysensors in this example). openhab will then publish the event to the mqtt broker on its topics (useful if you use f.eks. node-red for openhab rules)
