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

Hey,
I was not able to make it work 
@thomas-be How do you use the appdaemon app? I tried and failed too.
Well, I wrote it, specifically for my situation. There is also code to have it controlled with Tradfri remotes and so on.
I made it available more to serve as inspiration than as a working solution, sorry about that.

I’m currently working on a workaround to detect the current ‘state’ (speed + lights on/off) by using a power socket (Fibaro Wall Plug) and use the power consumption as an indicator.
Using power consumption as a feedback loop to detect the current state. This enables commands like ‘light off’ and 'speed 2’.

In my appdaemon app I have a state machine which mimicks the behaviour of the hood. I keep it in sync by swiching off using the “-” command, and each time I do this I add a few “-” extra. This is sure to switch the hood off, even if it would be out of sync with my state machine.
The only tricky part is the boost function, which is time limited. For this I also have a timer in my state machine which reduces the fan speed a few seconds before the internal fan timer would. That way I keep things in sync.
Downside of this is that you can no longer use the original remote. That is why in my code you will also find references to a Tradfri remote, which I use to control the hood and the lighting in the kitchen.
All that just to be able to control the hood with my smartphone 
.
Thomas.
@thomas-be That looks like the same route I took with my Novy Homey driver. That one even listens to the button presses of the remote and updates the state when a button press is detected. This way the remote can still be used. It also tracks the boost function timeout.
Using that driver, the remote button-presses were not detected at all times and therefore the state was out-of-sync regulary. Furthermore the hood itself has some buttons and I’ve got a novy induction cooking unit with buttons to control the hood. I want to keep using all of these. By measuring the power consumption I’ve got a quite precise indication of the actual state of the hood.
The current implementation actually works quite well:
pressing some random buttons in HA & on the remote
When I activate the ‘movie’ or ‘sleep’ scene, I also want to turn of the hood lights.
And I also measure the power consumption of the induction cooking unit and automatically set the speed of the hood.
