I have been creating a sensor network at a local high school and the mysensors project is basically what makes it possible. I just launched a website on amazon documenting some of what is deployed with live graphs.

At this point we are mainly just monitoring and collecting data, so my controller is a very simple node-red installation that saves data locally and transmits data via MQTT to mosquitto runing on an Amazon EC2 instance. Another installation of node-red again saves data to InfluxDB and Grafana displays the data very nicely.

We have three active nodes. One sensebender node running off battery and another solar powered node. A sample of the graphing is below. Check it out. The site is new so I suspect there are many typos and broken links. Thanks again to this community for helping me.

@rickmontana83 I have been anxiously awaiting openHAB2 for several months now. It is supposed to solve most of your issues although still java but optimized for devices like raspberry pi. I believe ReleaseCandidate2 was scheduled in the next week. However that is all marketing at this point.

To me openHAB seems to have the biggest user community and industry support which is why I have been waiting for openHAB2. I completely agree that asking new users to create sitemaps, xml files and download an eclipse app is just too much.

I hope openHAB2 delivers.

I have been playing around with the MQTT Gateway and Node-Red. I started with what user @Heinz did in a different forum topic however I am hoping to use MQTT.

First of all, node-red is a dead simple way to monitor MQTT traffiction. The question I have is about the messages created form the MQTT gateway.

I am only getting messages that "set" data. For example

{ "topic": "MyMQTT/20/0/V_HUM", "payload": "53.5", "qos": 0, "retain": false, "_msgid": "a3f256c8.5c0da8" } 

but I never see any presentation messages or ack messages. I took a look at the MQTT code but I don't know C++. Is there a difference between the serial gateway and the mqtt gateway? Meaning is there more functionality in the serial gateway?

By the way the vis app for node-red, https://www.npmjs.com/package/node-red-vis
, has some nice functionality. Pretty easy to add switches. I think you need your sensor IDs to be static but I think you could easily create a widget to display sensors that are new.

I can do some testting also. Happy to help.

I noticed the web page on connecting the radio does not match the troubleshooting section. Connecting a Decoupling-Capacitor on the Radio page says 4.7µF but the troubleshooting page says 47µF. Seems a bit confusing.
