New RFXcom device to Domoticz

[Sushukka]

Hello,
Had a discussion with RFXcom about Cotech/Kangtai remote wall plugs sold at least in ClasOhlson:
http://www.clasohlson.com/fi/Kaukokytki ... me/36-6010

They nicely implemented this protocl to the newest 1013 firmware of RFXtrx433E which probably will be available soon. Have tested it with RFXmngr and it works fine. Here is the log of all four on/off channels of one remote:

Transmission works with the newest RFXmngr version 18.0.0.17 by choosing Lightning5 and Type: Kangtai/Cotech. First level of ID field is grey so I need to only put my 22 and F6 to ID field and unit code + on/off --> transmit and it works like a charm.

However, I'm not sure if I'm a total noob with RFX or doesn't Domoticz fully support this new device addition because I can just register one button per channel. Here is one registration:

RFXCOM 433,92Mhz Transceiver 0022F6 2 Garden Light Lighting 5 Unknown

.
It shows like my other lightning switches, but when clicking it, it seems to send only the "on" command and doesn't update the lamp/switch icon to "on". It never sends the "off" command. When trying to register the off button of the same channel it says that this code is already registered to "Garden Light". The actual on command is sent correctly as the garden lights turn on. Seems that there are some very tiny problem somewhere but cannot find where.

Here is log from Domoticz:

Hmm, is this the right place to put this kind of requests? According to Domoticz wiki this should be one place to do that.

[b_weijenberg]

Use the latest Domoticz beta version.
For the RFXtrx433E use Ext2 firmware and enable the Lighting4 and AC protocols.
When you push a button on the Cotech remote it will be received as Kangtai in Domoticz.

[Sushukka]

Thanks. I'll try this as soon as I get my current sensor project implemented to Domoticz.

All of a sudden I notice this device in domoticz. As far as I know I don't have anything with Kangtai / Cotech subtype.

[joostvanderlinde]

In my quest for cheap but reliable KaKu clone switches (and because they are ofter sold out at the NL Action store), I recently bought a set of
"uniTEC 48110 Funkfernschalterset 3+1" from Amazon

For some reason I cannot get them to work with Domoticz V3.8153 (tried with latest beta as well, same result).
I upgraded my RFXtrxe to the latest (1022) Ext2 Firmware.
In RFXManager I can catch commands from the remote and the plugs react to a command.

Code: Select all

Lighting5 command
================================================
Packettype    = Lighting5
subtype       = Kangtai, Cotech
Sequence nbr  = 10
ID            = 0102 decimal:258
Unit          = 1
Command       = On
Signal level  = 0  -120dBm

Remote:
------------------------------------------------
Packettype    = Lighting5
subtype       = Kangtai, Cotech
Sequence nbr  = 32
ID            = 830B decimal:33547
Unit          = 1
Command       = On
Signal level  = 7  -64dBm

In Domoticz I activated both AC and Lighting4

For some reason, any command from the remote is not picked up by Domoticz
Also, sending a command from Domoticz (AC protocol, what else to choose as I do not see anything that resembles Kangtai or Cotech ) is not picked up by the plug (in learning mode).

I have the feeling I am missing something here.....

Note: I use two other types of plugs:
Promax from Action using IT protocol, working ok
Flamingo from Action using AC protocol, working ok

[b_weijenberg]

Kangtai is controlled by Lighting5 - Kangtai, Cotech in RFXmngr.
I guess you need to receive the remote to create the Kangtai device in Domoticz. Enable receive of new devices in Domoticz and try with only Lighting4 + AC enabled.

[joostvanderlinde]

OK, tried it with just a few protocols enabled, but on my NL Domoticz system and with another remote of the same kind.
This one is now recognized as PT2262 instead of Kangtai/Cotech.....
Difference between the two RFXtrx is the firmware: Not picking up the Unitec remote in Domoticz (but it does in RFXMgr as Kangtai/Cotech ): 1022
Picking up the Unitec remote in Domoticz (as PT2262): 1012

There is no way to manually add Kangtai/Cotech or PT2262 devices in Domoticz?
As I can now only remotely access my other Domoticz system (in our holiday home abroad), I would like to setup the device based on the codes I was able to learn the switch with RFXmngr...... Any tips on that?

[joostvanderlinde]

In my quest to be able to manually define addresses for receivers tried to open a backup of the Domoticz database.

The only table that seems to record the actual address and type of a device is "Devicestatus".
So my guess to solve my issue is to:
1. Catch a code in Domoticz from a remote that is compatible with my receiver
2. Change the address of the caught device in the Domoticz DB to my liking
3. Learn the new address of the device in Domoticz to the receiver

Any experience with this?

[joostvanderlinde]

I think I succeeded in changing the Domoticz DeviceID/Type/Subtype of a switch.
To avoid any risk with using eg. SQLite3 browsers, I created a small Python3 script to accomplish this. The script also runs on Python 2.7!
Note:
1. You can only trigger switches that are supported by your hardware. I use RFXCom, to the below is based on an up-to-date RFXCom.
2. If you use this, you still might end up wrecking you Domoticz db, so please be advised to make a good backup beforehand!!

Note: You need to have a switch defined in Domoticz beforehand, ie. you need to know the ' index' by which you can identify the switch. You can create a switch manually in Domoticz (Switches screen), make sure you link it to the correct hardware (e.g. RFXCom). The other parameters (Switch Type, Type, ID and Unit code) can be set now to "anything you like" as they will be set with the script provided in this post.

The script takes a number of parameters:

• index: The IDX from the Devices screen, this is he key used identify the switch for which you want to set the new values. Mandatory

• id: The device id that is (to be) recognized by your switch. Optional

• unit: The unit that is (to be) recognized by your switch. Optional

• type: The protocol type your switch responds to. Optional.

• subtype: The protocol subtype your switch responds to. Optional

The script will (based on parameters provided) just retrieve values, or update any combination of device id, unit, type, subtype.

The exact formats of the id / unit are not known to me, but you can figure those out using RFXMgr.
From the Domoticz source I noted a few values for type/subtype (have to be provided as decimal (not in hex!)
As my issue focussed on Lighting 4/5 and PT2262/Kangtai, I only provide these values here, please check the domoticz source (RFXtrx.h) for other valid values:

• Lighting5 = 0x14 (decimal 20) => Type

• Lighting 4 = 0x13 (decimal 19) => Type

• Kangtai = 0x11 (decimal 17) => sType

• PT2262 = 0x0 (decimal 0) => sType

The script accepts all values as long as they comply to the datatype
