Experience with automatic radiator valves?

Any News on the reverse engineering on the Honeywell?

Good thinking Pieter, before we all rush out to buy 30 Danfoss valves [:D]

Pieter,
No News yet. Last week I blocked in the process decoding the data. This week I'm busy developing a special sensor device for a friend of my. Next week I will have a look again into the Honeywell stuff.

 Does anybody have any experience with them and with hooking them up to a home automation system?

I'm currently considering the Honeywell HR40 and HR80. The 80 has a wireless receiver (and transmitter?) in it,
<hr height="1" noshade id="quote"></blockquote id="quote">

A bit late, but a quick review for the hometronic system. Hometronic can control a lot of zones (about 17 comes to my mind). I use it as separate system.

The units (by units I mean, units on the radiators) communicate two ways. So the main unit can control your heating device (simpel on/off, no opentherm).
There seem to be 2 different systems. The system which is sold in the Netherlands uses modules (main, comfort, security..) This requires serious cables between the modules and the main control unit. Therefor I've chosen for the german version. This is far simpler, but lacks the security option. The main unit only requires power

.
Programming is very easy.
I've had one unit with bad reception (see other post) but that's more or less solved.
An other problem is the closing of the valves. Sometimes it looks like the unit can't completly close the valve. This depends on the valve it has to close and not on the unit (switching units doesn't reduce the problem). I used some "lockspray" on the valve, and it looks like it has solved teh problem.

Hi all!

I'm already a while busy developing home-automation software for my Arduino. I'm able to switch lighting on and off and various other stuff.
I just opened the remote of my Central-Ventilation system and found almost the same components as MindBender found in his remote.
Now i would like to buy a RF sender/receiver from Conrad, but they sell FM and AM versions of RF modules. Which one should i get, to be able to receive and send the same signals as the remote? This is probably for most of you a simple question, but i don't know the answer and don't want to buy the wrong stuff.

My goal is to switch on the central-ventilation when the humidity rises in my bathroom.

Thanks in advance

Any update guys?
Cheers

I'm also really anxious to hear some News about this topic...
I also posted in another thread about that trying to control my Home Ventillation systeem. It works on 868,3mhz, but i'm unable to receive some good signals...
I bought a 868mhz On-Off-Keying-modulation receiver... Let me guess.. The wrong modulation-system?

Hi all,

I think many of you will find useful this:

Seitron Italy is selling wireless thermostats with a special receiver with RS485 bus output for home automation.
Standard installation is made of one thermostat for each room, one active antenna connected to a multichannel relay module.
DTPF85BC thermostat
DAPF84 active antenna
DLP841M relays module

The RF receiver is actually in the DAPF84 active antenna which forwards commands via RS485 to the relay module.
DAPF84 can be configured to talk to a pc instead of the relay module, the protocol is available upon request.
Your pc (any microcontroller board) can get temperature, knob position of any room in your house.

Hope this helps

the solution looks great but the only problem that it lacks the control of the valves.
thanks for the hint
cheers

Hi MindBender
The smd marked as K110 B3 is an Infineon TDK5110 ASK/FSK Transmitter 868/433 MHz. Also used by Honeywell in PIR motion sensor and keypad in Domonial alarm panels.

Looking at the other products of Honeywell I would think that they are using the Lontalk protocol as described here http://www.echelon.com/developers/lonworks/protocol/
To me it seems a good idea to contact Honeywell before spending lots and lots of hours of reverse engeneering. Has anyone tried this already?

Hi Guys,
Just wondering if anyone has acheived anything with the Honeywell protocol yet or whether it has vanished to the 'to hard and not enough time' basket. I would be more than happy to add my thought power to the mix if anyone is keen to crack this one.

Cheers

Is it possible to use the Honeywell CM57z and the CM67z together in one system with one HC60NG module?

At conrad I saw a HR80-RT is this the same as the HR80?

On both questions Honeywell NL told me that the products are unknown in NL so no information

Can anyone here clarify this for me?

Thanks in advance.

I thought someone may find this useful, hence this post.

I posted before that I have 14 Honeywell HR80UK valves plus 2 CM67Z controllers creating 4 zones. I have been impressed with the HR80 valves so, about a year ago I replaced the 2 CM67Z's with the Hometronic manager which allows independent control of all 14 valves.

I still had the problem of no Homeseer integration and the only solution seemed to be the very expensive (1000 GBP +)WebManager interface available from Sensible Heat, which would then only have provided stand alone web control of the Hometronic manager. The Hometronic system is a pretty neat home automation on it's own and very reliable, but the components are just so expensive (over 100 GBP for an appliance module). The plus side is that many components are 2 way giving status feedback.

I did approach them (Sensible Heat) asking if they would sell just the USB interface so I could write my own Homeseer plug-in, but this was not possible as they would then have to divulge the communication protocol between the PC and the USB interface, which they were not willing to do.

Anyone who has the HCM will know that you can set lifestyles which are basically a collection of settings to apply. Honeywell also have a 5 channel digital input module which can tell the HCM to activate a lifestyle based on the value of any of its inputs. So, I have coupled one of these modules up to an RFXIO (although any output will do) and I can now activate lifestyles from Homeseer.

Not full room by room integration I know, but at least I have some control over the heating from within Homeseer.

Paul..

Did you guys see this one ?
http://www.evohome.info/

It's the new evotouch controller from honeywell, wich can control 8 zones max.
Lets hope the usb port on it isnt there only for future updates

i am ordering one this weekend and will post my expierences when its up and running.
