Hi Antrax, Well, X2D for shutter is probably a bit more secure (rolling code). To be sure, you will have to buy an USB TV Tuner SDR compatible key (something like the keys you will find here : http://www.rtl-sdr.com/buy-rtl-sdr-dvb-t-dongles/) and capture, with rtl_433 tool, messages sent by your ...

@gbraux2, I fixed error with pyDeltia.py when between 23h30 and 00h00. It was a wrong convertion in chauffage.ods 24:00:00 was converted to 00:00:00, I simply changed cell type to Text. Note that with chauffage.ods/chauffage.csv, you can choose any time to do actions. By default, you can set orders ...

@gbraux2,

Not sending "Turn On" message is a choice, I find this useless.
But implementing this is not really difficult, it's just another message.

SixK

If you send Zone1 Off, and then the 2nd message of Sun1 or Moon 1, your heater will turn On. As I said, 2nd message is to turn On or Off heaters. If you send Sun1 or Moon1 message you are supposed to want your heaters to heat, so they turn heaters On. In fact you have to keep in mind that Deltia ...

@gbraux2 and others,

Could you please publish your Deltia captured messages ? (For sun, moon, etc...)
I think the more we will have messages, the more we will be able to understand X2D protocol.

@gbraux2, I'm far from being a RF Expert, to be clear, I'm nearly an electronic newbie. :) But as I played with RF 433 temperature devices, I can says that with a low cost RF433 module like you can see here http://electroniqueamateur.blogspot.fr/2014/01/modules-rf-433-mhz-virtualwire-et.html pulse ...

@gbraux2, Deltia emitter always send 2 messages of 74 characters length. (repeated 2 or 3 times at 30 secondes intervals) usually : 1rst message is to swtich ECO/Confort mode. 2nd message is to turn On or Off heaters (so it always send "turn on" message except if you explicitly want to turn heaters ...

Hi guys, Nice to see some of you are trying to manage heaters with rfbee. I've turned on my Raspberry Pi (with my RFbee connected on it) a month ago and everything is working fine and stable. I keep my Deltia emitter in Auto Mode just in case, but it could be turned off. Edit==> Well, I've just ...

Yes, that's something that is highly expectable.
They probably use Rolling code (and maybe a different protocol/modulation) for Curtains and alarms.

But as X2D is quite old, messages have to be captured to be sure.

Hi,

Added a minimal WEB IHM on Github to control X2D Heaters from anywhere :
https://github.com/SixK/CC1101-X2D-Heaters

@ervplecter,

If you already have captured associate messages, send me your "X2D_Heater_Messages.h", I'll try to associate 1 of my heaters and I'll be able to check if your messages are Ok or if something is wrong.

SixK

@ervplecter, Here is traces when I send "Sun3" command : D:\pyRF>pyX2DCmd.py Sun3 >>Starting CC1101... Initialize and set registers. Setting PA_TABLE. CC1101_PARTNUM 0 CC1101_VERSION 20 CC1101_MARCSTATE 1 device initialized >>Sun3 >>end of line 0 sent ok :) Sun3 SixK

@ervplecter, I'll not be at home before Friday, so I will not be able to take traces, but when you send to RFBee a command such as Sun1, you should have CC1101 init message, then something saying a message is sent with a OK statut. My github is supposed to be uptodate, I just hope I did not made any ...

Actually we have no clue if X2D messages and protocol are exactly the same with curtains. (but we may expect that X2D curtains works the same way) You will have to be sure about Frequency used my your devices : 433Mhz or 868Mhz. (or both) 868Mhz should be ok with something like RFBee, 433Mhz may ...

@ebretteville,

I'm not sure to understand what you mean.

Current Web interface functionnalities are :
- Switch between Auto/Manual mode
- Switch between Eco/Comfort mode for Area1 and Area2
- Upload new planning (only .ods files are supported)

SixK

Hi,

I should not be far from been able to release a minimalistic Web interface to control Heaters.

I still have some tests to do with my Raspberry as slave/client, some code refactoring/reorganizing and maybe translate everything in english.


Here is a first image : SixK

@ervplecter, Clearly there is no rolling code, to my point of view, X2D is now a quite old protocol first developped for PLC (CPL) and then adapted to RF just replacing wires by emitter/receivers. When X2D started Delta Dore was probably a small enterprise. They probably did not anticipated that few ...

I think it may have small differences between RFbee and your CC1101 module, RFBee is an arduino + CC1101 (V1.2 has an Atmega 328). I don't remember if RFBee use internal clock or an external one, but you may have a different clock on your CC1101 module. If I have a good memory, you do not set CC1101 ...

Yes I think you are right.

Ok, difficult to say what's wrong, Antenna length should not have such an importance and Deltia Receiver should be tolerant to frequency deviation. My fear is about the possibility to program CC1101 module processor through arduino, in my case I use an UartSbee, a dedicated module to send firmware ...
