I've been using a Raspberry Pi to monitor my hives for a while now. I have a couple of BS18B20's and a DHT22 in each of 2 hives so I was interested to see that's rather similar to what's been done here. I also have a camera looking at one of the hives - I want to try using OpenCV to track traffic but, probably in common with everyone else, I've had too little time so far. I also want to add load cells via a HX711 but, again, this has stalled.

Anyway, I upload the readings via MQTT to IBM's Bluemix PaaS, where the readings are stored, and from where the data are delivered to the web page at BeeSpi. The Bluemix end is programmed using NodeRED.

This monitors the 2 hives in the bottom of my garden where I have power and WiFi. I'd like to make it work for an off-grid location, perhaps by using solar cells and GPRS.

Thanks for sharing your work on your blog!
