I’m working with Craig on an MQTT client (very early state on http://www.squeaksource.com/@gWFeIvLx-rTHKE2R/Gtrt3pje) to read it but then what?

I guess I ought to store some amount of collected data so maybe it’s time I got to grips with Magma. I’m interested in all ideas that might lead somewhere fun with this. With those ESP8266 wi-fi enabled sorta-arduino things so cheap and easy to set up there must be a gazillion interesting things that could be monitored and analyzed and graphed and indeed actuated in response; let’s not forget that MQTT works both ways.

Or a strain gauge on your security fence alerting you that something heavier than 20 pounds has climbed over so the remote gatling needs hotting up?

>> [1] Pi model A+ with gpio attached interface board for rain bucket, wind speed/direction, outdoor temp/humidity, indoor temp, RTC and USB attached Ethernet interface to POE adaptor. WiFi wasn’t practical due to metal roof. Besides, POE means I can hard-reboot by pulling a plug in my server room :-)
