Newbie alert: sensor data not showing

thecricketer last edited by

I toyed around with this project some time ago and put it down but recently picked it back up. I build my first serial gateway (RPi) and also my first sensor was for temperature/humidity (Arduino Nano). I followed everything by the book and everything talks no problem. In the openHAB log the sensor is sending data every 2 minutes and I can see it updating. Awesome! Yay me! Here is my question. How do I “see” the data? When I go into HABmin or any of the UIs, if I try and add a widget or a gauge, there is nothing there to “select” or tie it to. No sensors show up, etc. I know it’s updating the data but what am I missing?

To add another option to this thread. I have not yet used them but I am collecting these. They look like they are made for these types of sensors

@TimO No Sweat, found it - it was because the node was powered on before the gateway and presentation didn't go well...

@ben999 Check out Serial Protocol I have four Arduinos. Each has a different MY_NODE_IDs (I use 130, 131, 132, 133). Each has four sensors: moisture, humidity, temperature, and voltage each of which has a CHILD_ID: CHILD_ID_MOISTURE is 0 , CHILD_ID_HUMIDITY is 1, CHILD_ID_TEMPERATURE is 2, CHILD_ID_VOLTAGE is 3. When an Arduino makes a measurement, it sends that measurement to a unique MQTT topic. In the case of the Arduino with MY_NODE_ID of 130 that is sending the moisture measurement, that MQTT topic is mysensors_out/130/0/1/0/35 and the message is [something like] 760 (35 is the value type) Similarly, when a controller sends a command to a device (Arduino), the topic is unique. If you have two actuators with the same MY_NODE_ID and CHILD_ID (MQTT topic) there would be confusion as to what you want each actuator to do. Likewise, if two sensors had the same MQTT topic, how would the controller know how to handle the data.

@chrishiscox said in OH3 Serial Gateway Problem: I tried and tried with my serial gateway, and never got it to function porperly. The serial port was working I could see it and data, but OH3 just refused to recognise the data. After a week, I decided to abandon the serial and flashed a esp8266 attached the nRF to it and bobs my uncle as we say. It goes via MQTT, so takes a little more settting up but works fine. If you want more info I will dig out the pages I used to make it work. Hmmm, the pi OH is running on already has an active MQTT broker. So you got me thinking: Wouldn't it be possible to use the MQTT gateway instead of the serial gateway? It should be able to translate radio messages (Hope RF69 in my case) to mqtt messages which are already recognized by OH. I'll have to find a spare pi and try it.

Hi @CyborgAndy many thanks for providing the binding update for MySensors 4.0.4! I upgrade my OpenHAB 3.4.4 a few minutes ago to 4.0.4 successfully with your binding update. I use a USB connected serial-gateway. The OpenHAB manual installation upgrade works perfect. I need to do afterwards the following steps in the Karaf console, to get the gateway online again, after the update: feature:install openhab-transport-serial feature:install openhab-core-io-transport-mqtt feature:install openhab-core-io-transport-serial-javacomm Many thanks again! kerberos
