Let's Control It

Hello,

I am new to the RFLink world, to the Arduino and to the RF433.

Having started home automation (with Home Assitant), I am trying to automate my pellet stove (Piazzetta P956). I saw that the remote control communicates on the 433.92Mhz frequency band. So, I choose the RF option rather than the RS232 way.

After much research and testing, I was able to make an RFlink gateway with an Arduino Mega Pro 2560 + RBX6 + FS1000A.
I can clearly see the raw frames pass. As expected, they are not supported by the current RFlink firmware.

My question is: is it possible to ask the developers to help me decode the protocol or is it a waste of time because this device and this request is not common enough?

Thank you for your answers

Hi,

Check: http://www.rflink.nl/blog2/development
That explains what I need.
With the raw packets it should be possible to see if it is something easy to implement or not.

We are currently working on a new site to streamline devlopment.

Thank you for your quick reply.

I had already read the link you just quoted to me and indeed, I thought I was starting to provide you with information.

I will therefore go over this in detail.

Hi,

I've the same idea than you.
I have a pellet stove piazzetta p943m and with the last upgrade from micronova, i can't integrate the stove with the ip module.
And i don't want to try the solution with esp on the RS.

I've seen that the remote use 433mhz.
Before to build a rflink, i would like to know if you succeded to decodate and emulate your stove in HA?
I hope you did it .
Thanks by advance for your feedback and your help.

Good morning,

Sorry for the delay

Unfortunately, I didn't have time to pursue this.
I got for the SwitchBot solution which presses the button behind the stove. However, even if the SwitchBot action works every time, the stove every other time does not want to stop.
This is why I would like to return to this 433Mhz option.

There, I'm going to put the SwitchBot directly on the remote control. I'm sure it will work every time. It's not great but it will help out this winter.

The action will be: Home Assistant --> (Wifi) BTproxy (Bluetooth) --> (Bluetooth) SwitchBot (Mechanical Action) --> (Mechanical Action) Remote Stove (433Mhz) --> (433Mhz) Stove

We can do better

We are still looking into this.
One problem seems to be that the RF signal for ON and OFF is the same.
At least the logs I got so far are showing only 1 packet for on and off..
It would be good if anyone can confirm this is the case.

Anyway, if so then due this this and the fact that RF packets can collide with other RF packets (like temperature sensors etc)
there is no guarantee that the ON or OFF signal is received and processed by the stove.
to visualize:
when stove is off
send ON /signal collides/ stove: no action
send OFF /no other signals on air/ stove: turn ON

Btw, the switchbot solution is not really needed. RFLink has IO pins that are directly available for switch settings.
This means that if you connect the IO pins to the remote control pcb you can control the stove via Domoticz/HA etc. directly without delays.
The RFLink IO pins are available as a regular ON/OFF switch. You can use multiple pins to also control the other states the stove might have.
