Update 21-5-15

Just a bit of a quick update on everything:

After running alright for about a month the Raspberry Pi in the doorbell locked up a few times and then stopped booting, from what I can tell my estimation of voltage drop over the PoE setup may have been a bit off and fed the Pi a bit too much voltage so I’ve bought a LM2596S step down voltage regulator off eBay and will run 12v over the PoE and then regulated 5v into the mini USB of the Pi.

Doorbell system is now back up and running and hopefully should remain stable now.

I’ve done a bit more work on the internal house website to add the ability to quickly see the pictures taken from the doorbell camera as well as current data from my uRAD Monitor.
It gives a good overview of current weather,  sensor data and last ring of the doorbell. As more sensors are added I’ll add them in here. Clicking on each of the sensors brings up the last 100 entries and clicking the front door brings up the last 20 doorbell presses.

uRAD Monitor section give the current radiation counts per minute as well as an average and the links below create graphs showing CPM vs wind, rain fall and temp/humidity.

The software that came with the weather station was pretty basic so I got Weather Display which is much more powerful and can export data directly into mysql as well as upload to a website, etc.

I’ve found the wireless from the weather station to be a bit unreliable hopefully just due to some flat batteries.

I’ve added new graphs to match weather data with radiation data from my uRAD Monitor, you can see flat sections in the graph where the weather station has not reported back correctly:

Rain vs CPM
Temp and Humidity vs CPM
Wind speed and gust speed vs CPM

A bit more work has been done with the home automation system. I replaced the 4 channel relay board with an 8 channel board which will do low voltage operations (12v/5v) and have re-purposed the 4 channel board for 240v switching as to keep LV and HV separate.

This has allowed adding of several more devices without buying expensive Insteon modules for each device.

Here are the different “rooms” in HCA now:

Kitchen
Lounge
Bathroom
Backyard

The front yard “room” now also includes buttons to capture and email a picture from the doorbell camera as well as start a live stream as seen below:

Currently finishing off the 5.1 system in the lounge and after that work will begin on expanding the rack to a floor to ceiling 19″ rack.
