jcw (father of the Jeenodes) is still working on his home monitoring/home automation system – and he is moving it in a interesting direction, partially along the same lines as I have been (slowly) moving my own monitoring system.
He’s now moved a significant portion on by using Go – something I have not looked at yet.
Here’s where I’m headed with all this:
Flow is the foundation for it all: dataflow programming is – p e r f e c t – for real-time apps such as HouseMon and Tosqa. The fact that it’s called 0.1 just reflects my inexperience with it all. But there’s no way back. There are lots of “worker” components in the 0.1 release already. They don’t really belong there, but it was easy to develop them that way. These will be moved to JeeBus soon – due to the registry, this won’t affect the program code (just a few “import” lines).
The other thing which hasn’t changed is “developer mode”. This is a setup now in JeeBus, which adds node.js and “gin” to the mix, to support live reload while making changes. I’ve briefly stepped away from it while hacking on Flow, but will definitely bring it back to the foreground once HM/JB and client-side development enter the picture again.

The red bandwidth usage line is the main wireless router in the house – in the living room.
We are running a multitude of home automation systems – but the one that communicates with all the heating is still FHEM, one of the few that can actually communicate with our FHT80b thermostats.
Here is tonights picture of our houses heating :
The green line show how open each actuator (aka valves on our radiators) are in each of the 3 heating zones in the house.
The red line is the actual temperature in the zone.
There’s another part to it as well, controlled by a set of bespoke routines for turning on and off the main valves for the hot water and the heating water circulation as well. Included in this is software for turning on and off the circulation pumps.
Who should have thought that a smoke alarm could create so much hilarity
The new Nest
speaks to you in a almost perfect female voice saying things like :
“There is a lot of smoke in the kitchen, the alarm may sound, it’s very loud”
whereupon you can see whoever is in the kitchen when this happen leaping around waving their arms to turn the alarm off….
In the continuing discovery of the Domoticz software I bought a couple of Home Easy HE305 magnetic door switches
To try to get them working I first of all had to switch on the Home Easy EU in the Rfxcom control panel like this
and the use the “Learn” button on the switches tab. This recognised the switch as long as I was very close to the Rftrx transceiver.
But – it does not work reliably. It updates the log for every time I remove the magnet and again when the magnet is close enough, but it only sporadically updates the panels.
So I may have to raise a bug…
UPDATE : Found the problem – edit the switch to se the correct type like this :
This changes the display to :
Experimenting with Domoticz running on a Raspberry Pi – with a few routines pulling data from the house monitoring systems
(Clink for larger image)
So in the end I bought one of these transceivers
It can communicate with a very long list of 433 Mhz devices – the full list is here .
And I plugged it into my Raspberry Pi running Domoticz
I can see my weather station sensors – so now I may get around the problem where my receiver (inside) stopped working when the temperature in the room goes below 15 degrees Celsius (!)
This is really interesting for our household full of iDevices…

The Dust sensor arrived tonight for the Air Quality egg arrived today – and has now been installed, and the feed is working.
(Click for larger image)
The measurements seem a bit wrong though – possibly the Dust_r0 of -1 is somewhat wrong.
Btw. I followed the instructions here for the physical installation. I will post pictures later.
This may be of interest due to the combination of technologies and the fact that it is open source…
