@gohan Ah really? I've loosely been following last i saw there was a proof of concept mentioned.

I use MQTT and Openhab2 - I find it more flexible then the Ethernet GW but yes you need to have a good understanding on all systems I suppose.

Somethings to note

• MySensors binding doesn't support MQTT gateway as far as I know, you need to use the MQTT binding and configure your OH items accordingly.
• MySensors binding is in the IOT market place and not openhab-addons
• You'll need to assign node ID to your nodes manually.

Not entirely sure what your problem is here but don't think you've got all the right pieces for the puzzle yet.

You need to change the MQTT topics in the OpenHab MQTT config.

MYS 2.0 is publishing data to this topic.

MyMQTT/27/5/1/0/4

However openhab is subscribing to this topic.

MyMQTT/27/5/V_PRESSURE

Hope this helps.

The keypad will not be used to enter numbers. I will place a sticker over it converting the text on the switches to functions as "turn party lights on", "switch heater on", and "turn on garden lights for 5 min". These buttons will be coupled to certain actions by the controller. I'm using Domoticz on a Rpi.

Nice idea. When you do it could you provide a photo? Like to know how clean it looks.

I was wondering about this but currently don't have any nodes that need to report errors. I thought though I would wrap the error in a string including a prefix as well as importance of the error and send it back to the controller via S_VAR

I use MQTT gateway and I would have NodeRed listen out for any string with the prefix and send me an alert or log the event depending on the importance.

Just an idea at the moment but might help you.

@sundberg84

In power input I would suggest moving GND to the middle of VCC/RAW so you could using a 2 pin block for GND/RAW like what is shown in post 205. Might cause tracing issues though for you.

Why? Because it was fun and it can be done

Ha, I agree with this! Just curious about the fun after connecting it up.

There was a Node Red update the other week BTW, version 0.15

I'd be interested to know what you have planned with Azure IoT once you've got the data in to it? Not had time to investigate myself.

I'd go with NodeRed in between a local MQTT server and Azure IoT as going direct to Azure puts a dependency on the internet connection.

@Meshx86 the openhab binding doesnt support MQTT as far as I know.

If you are using the MQTT binding then you need another controller/method to provide the internal functions for my sensors. I use NodeRed workflow to listen for ID requests and it provides them.

Or static assign them in the node stretch.
