868 Mhz Wifi RF module for MCZ Pellet stove

Question

Hi all,

I have a Google Home that I'd like to control my MCZ Pellet stove by voice command.

I have a remote for the stove that works at 868 Mhz, so I need a RF bridge that can manage that.

I've tried to google for such a device, but I can't find it, so I'm searching for en expert that can guide me. I'm a total novice on the subject.

I've found this device here on Farnell, but I'm unsure if it will work. My plan was to stick the USB part in my router and use Ifttt to control the command.

USB Gateway, Wireless Transceiver Module, 868 Mhz

regards

Pierre

Life is much more complicated than that and unless your stove uses the Enocean protocol and you run a PC with the Enocean software, the module you suggest can not work. The truth is that manufacturers use all different sorts of control mechanisms at these frequency and do not usually document it. To make something work wolllikely need you to open things up, investigate the encoding of signals on the air (e.g. by using an SDR radio), reverse engineer the commands themselves and re-implement on a microcontroller and transceiver chip combination. Then you need to get the combination on the network (securely) in a way that Google Home can talk to - you don't want someone random on the internet messing around with it. It's always easier if it is a model someone else has done the hard work for, but as someone who has reverse engineered a number of devices, it is time consuming and does require some level of expertise. - Gough

I understand your motivation but will your insurance cover your loss if a fire in the stove was the cause? Knowing insurance companies, they would love to discover a modification that gave them a way out of having to pay.

Hi Pierre, I stumbled upon a similar issue, although it was not a stove in my case. I could not find the 868 Mhz - wifi bridge for Google Home. The idea just flashed through my head this evening. May this be helpful: https://www.youtube.com/watch?v=8h5ZCviPSvc I wanted to make a c# app that would control 868 transceiver via USB that would control garage doors and automatic garden gate. So I got one from China, and I also acquired sub gigahertz radio spectrum analyzer and decoder from France. In the end, the simplest solution is the best Cheap universal programmable 868 remote can do the job and can be controlled by another potential-less relay (by soldering two wires to two contacts that are switched by pressing the button manually). That relay can be then operated by other devices, services... Even in the case of floating-code remotes is the situation same. You can in most cases pay for another remote from manufacturer of the product (car, home alarm,...) and gut one out like this BR, Patrik
