As some of you know, I Joined Rackspace's monitoring team about 10 months ago.  They have been very gracious to let me spend large amounts of my work time building and maintaining Luvit. (Which is used in production by the monitoring agent.)

Recently I decided to try and find a way to incorporate this free monitoring service with my garden sensor project. I'm happy to report this actually works really well.  The key is to deploy a simple relay server somewhere on the LAN. I'm using a Raspberry PI in my home office. (These are also my luvi build boxes for armv6 and armv7.)

IoT sensors tend to be very low powered devices.  I've had most success recently with the [Particle](https://www.particle.io/) boards and the [Esp8266](http://www.esp8266.com/) chips.  The ESP chips are cheaper, but a little rougher on the edges.  Both of these feature 32-bit microcontrollers with WIFI capability built-in.<commit_msg>Publish iot-relay article<commit_after>{ title = "IoT Sensor Relay",
