I have a Novy hood. It works through the RFXcom. When I send a signal through the RFXcom-manager, the hood comes on.
The question is now. Can I integrate the Novy cooker hood into Home Assistant? Perhaps this is a question for the designers of Home Assistant. In Domoticz they say that despite the fact that the Novy works via RFXcom, it cannot work in Domoticz because of the very different coding of the signal. Does this also apply to Hassio?
If not, how do I integrate the Novy?
I just contacted rfxcom.
And Bert Weijenberg
@b_weijenberg I suppose it’s you 
I don’t understand.
On this forum, you’re telling me to contact rfxcom, but when I contact them you’re answering to check the forum ? 
What should I do to make it work ?
Perhaps only something I’m not doing correctly ?
Thx
As I told you just by email, this is only the case when Novy could not be controlled using RFXmngr.
As I said in my first post 
So… now ?
What am I doing wrong ?
Hello amans,
you have an RFXtrx433XL: were you able to pair your Novy remote control in HA?
If yes, what are the code lines that must be entered in HA to order the Novy hood?
For my part, I have an RFX433E which does not receive the signal from the Novy remote control. You need an RFXtrx433XL to do this.
In the meantime, thank you
Hi Patric,
I think I’m in the exact same situation than you here : RFXcom without transmitter
Still waiting for a solution too
I have one and was not able to “pair” it. Contacted @b_weijenberg about this and he said he would look into it. Hope he finds the time for it soon!

Thomas,
I contacted him live yesterday and he replied:
“The RFXtrx433E can only transmit Novy commands. The RFXtrx433XL can receive and transmit Novy commands. See chapter 2.2.2 in the RFXtrx User Guide. If you absolutely need to receive the Novy you can use the RFXtrx433XL.”
Today, I sent him this message:
"thank you for your answer … on the other hand since we cannot pair the Novy remote control because the RFXtrx433E can not receive signals …except passing through an RFXtrx433XL … do you know the code to put in Home Assistant to order the Novy hood? "
I hope he has the answer!
Otherwise, we will have to turn to HA developers
Pat
Indeed, my XL is supposed to be able to receive the commands but somehow it does not manage to decode them. So even though I have the XL, it is not working for me.

Hello Thomas,
RFXCOM replied:
"
If you transmit the Novy command in the latest RFXmngr you will see the hex code to use !! "
To tell the truth, I don’t know if he knows and if he really understands.
For this reason, I sent him this message this day:
" yes the hexadecimal code is in this form:

But my question is how to write it in Home Assistant?
For a Chacon switch, in HA, we have this:
#switchs:
platform: rfxtrx
automatic_add: true
devices:
0b11000000edeb5e0b010f70:
name: Switch
For the novy hood, how is it written?
You can give an example of writing in HA please."
I hope that will give us an example to order a Novy under HA
A beta XL firmware version 1043 has been sent to you.
Hi,
Can you send to me the beta firmware too so I can test?
Thx
Hi,
I received the beta firmware from @b_weijenberg and there is progress!
- RFXmngr now properly recognizes the buttons on the remote (light, +, -, power) I see them coming in the software and they are correctly marked.
- However, it still does not work in Home Assistant. This is (I think) because they are not switches or lights but a Fan control and I’m not sure Home Assistant understands what to do with it.
- EDIT: I also can’t seem to get debug messages in the log when a button is pressed on a remote which is recognized. I set
debug: truein the config but nothing appears in the Home Assistant log. Does anyone have this working?
So, yes, the firmware has solved the issues in the receiver but no, I still can’t use it in Home Assistant. This is something for the developers of the integration to fix.
Exactly the same situation for me with the same firmware.
OK for the fan buttons on the remote.
But what about the light button ? Same result in HA.
As soon as I can find the time I will try to do this using Appdaemon and direct serial control. For me that would work as I only use the rfxtrx for my Novy hood.
Thomas
One question from someone who has never integrated any RF device into HA and doesn’t own yet any RF bridge, why going for the RFXCOM bridge instead of other options like Sonoff RF or the BroadLink RM Pro?
Aren’t all RF bridges capable of sending and receiving messages from any source?
Hi, have you ever been able to get this working? I also have a Novy hood for some years now but never came around integrating it in HASS.
I ended up sending the raw commands to the RFXTRX with an appdaemon app, source is here: https://github.com/tnagels/novy_hood
