Just a quick high-level diagram of my Open Energy Monitor. Pretty much as standard except that my openHAB MQTT broker subscribes to the emonBase MQTT broker as a bridge, subscribing to the emonhub/# topics.
I have sat on the fence long enough with the route planner. My original intention was to develop the planner to incorporate all the functions needed for an effective route planner for electric cars. I published the site (see: http://www.evzone.org.uk/planner/ )and made available a prototype version that included probably about 50% of what I thought it … Continue reading EV Route Planner – Now Open Source
The article header image is courtesy of Open Energy Monitor – why not check them out as this is one of the main components in my Home Automation and Power Management System. http://openenergymonitor.org/emon/ Just a quick update on this week’s progress on the Home Automation and Power Management System (HAPMaS). Progress is going well. There have … Continue reading Home Automation – Good Progress This Week
I have been struggling to find a good power solution for my telescope and as the winter will soon be here, and along with it the longer nights, I needed to get on with it. I already have a 100Ah deep-cycle battery so I got myself a battery box with a built-in on-off switch, power … Continue reading Astronomy Power Box
Following trials today of the emonTH prototype (see previous post) it is clear that I have a lot of 433MHz traffic. This isn’t at all surprising as we have a lot of wireless devices including a Davies Weather Station which uses that frequency quite heavily. In fact, it was a close call to get 433MHz … Continue reading Home Automation – STOP PRESS!
So far I have outlined the basic strategy I plan to take regarding building a HAPMaS (Home Automation and Power Management System). Now it is time to get down to actually build something. In my Open Energy Monitor so far I have: an emonBase (Raspberry Pi and RFM69CW). This takes in data from the sensor … Continue reading OpenHAB and Open Energy Monitor – emonTH Prototype
It has taken 2 whole years of hard searching, viewing, making offers, pulling out of deals, getting excited and being disappointed but finally it has happened… Today we exchanged contracts to buy a house! More once we have completed because I shouldn’t say too much because I want to protect the privacy of the existing owner but … Continue reading We have bought a house!
Here is a good primer on mqtt… in case, like me before today, you had never heard of it!
Today has been a bit of a major step forward as far as integrating the various components go with the Home Automation and Power Management System or HAPMaS. MQTT is a way to send short messages between components. It is lightweight, quick, efficient. What’s more, it is a centralised messaging system that is independent from any … Continue reading openHAB and MQTT
In the last post I outlined the broad strategy I am taking in the design of my Home Automation and Power Management System (HAPMaS) which has led me to try to integrate Open Energy Monitor and openHAB. I want to keep the two systems apart as much as possible as that will make maintenance easier … Continue reading OpenHAB and Open Energy Monitor – Part 2
