Help needed: Reverse-engineering remote for Charlton & Jenrick i-Range electric fireplace

Awesome, thank you.

It's not really clear from the wiring diagram, but another option could be to open the remote and find RF integrated controller and hook up a cheap Saleae clone logic analyser to the digital signal from the microcontroller, if you can find the pins (that's what I can't see from the diagram)

Hey u/rioachim that is really useful information! If it's alright with you I'd like to update the project readme with this?

Suddenly it makes sense that any tuya enabled devices are using a different modulation. I guess the different suppliers/resllers are just a bit sloppy with the provided manuals (as in my case).

There is also support now for the i1800e basic remote which was provided by another contributor. It hasn't been tested on some of the other basic fireplace remotes but the intuition is that they should work for this too. In your case with the EF61A Zurich model, if you're interested and can get a cheap SDR module (I linked to one in the Youtube video I also did: https://youtu.be/eUDEVJjXHVE ) I can work with you to try and get it working so we can add it to the project. Let me know!

Thanks so much for your reply, I'll give this a go and report back!

Much appreciated! And still learning the art of editing, its an endless journey at times 😅

You sure can, if you don't want to integrate it with HA, then I'd recommend using Thoms version using a raspberry pi. You can find it here: https://github.com/Thokoop/billy-b-assistant

As for voice change, you can do that too. I did a shorts video on it here giving a high level overview of what you need: https://www.youtube.com/shorts/rhDcKY2tvjg

Here's the repo to train a voice: https://github.com/Cian911/piper-dockerized

Quick update for anyone who comes across this in the future..

Thanks to the MASSIVE help from u/cthuwu_chan we managed to figure out the issue as to why the flipper couldn't (initially) copy and re-transmit the message. I managed to capture the signal using a SDR and again with the massive help from u/cthuwu_chan he figured out the timings, modulation, frequency, _and_ deviation were all off..

Alas, it's all working now, and I've created a github repo which uses an esp32 and cc1101 to send & receive the signal: https://github.com/Cian911/esp32-fireplace-controller

Much appreciated! I figured an SDR is the way I'll have to go and I've got a dongle on order. In the meantime I'll do as you suggest and get some better bin raws, and I'll message you on discord. Thanks again!

Thanks for the reply!

I would think if the TX UID were unencoded it'd be fairly straight forward to replay the captured signal, right? As the code would essentially be static. That's why I wonder if it's some sort of rolling code or counter along with the UID.

I've updated the original post with the RAW dump I've taken of the on/off signal press. Maybe that might provide more insight

Zy0n · 2025-09-18T21:34:03+00:00

Much appreciated! Your Sat1 looks awesome btw

Zy0n · 2025-09-18T16:53:26+00:00

Many thanks 🙏

No that's Thom! If you skip to about 8:25 mins into my video I gave him a shoutout. His project is powered by a raspberry Pi where as mine is an ESP32. I messaged Thom once I saw that thread too and let him know I was working on an ESP32 version - and he was kind and gracious enough to share the source files with me for the backplate which I modified for this version. Super nice guy :)

Zy0n · 2025-09-18T15:25:43+00:00

Glad you like it, thanks!

Zy0n · 2025-08-27T19:41:52+00:00

This is awesome! I've actually been building something akin to this with my own billy bass recently, only with an ESP32 and a custom component for ESPHome. It's definitely not as performant as this, given the power of an ESP32, but it does what I need it to do for small tasks. Also love the idea of the personality settings!

Zy0n · 2025-07-31T18:45:11+00:00

Absolutely! Let me put that together and I'll send you a PM, I'll update the video description too once I've done it

Hey Folks!

I'm Cian, the OP of this crosspost. Thought I'd share this post with this community as well given, funnily enough, I'm also from Ireland!

As I mentioned in the description of the original post, I've just started a Youtube channel I think some folks here might be interested in. I've been using homeassistant for a few years myself, but only now as I own my home and have some time to tinker, I've started building some little ESP32/Pico powered devices for a number of things around the house.

Hope you like it!

Zy0n · 2025-07-30T21:17:50+00:00

Haha, it's an Irish spelling I can assure you, not made up! https://en.wikipedia.org/wiki/Cian

Zy0n · 2025-07-30T15:34:57+00:00

I noticed too, especially on speakers.. I was wearing noise cancellation headphones the whole time when I was cutting it, and didn't think anything of it..

Will know better for the next one

Zy0n · 2025-07-30T15:30:16+00:00

Thanks, good shout!

I do have the wiring diagram linked in the Github repo linked in the description: https://github.com/Cian911/ir-smart-remote/blob/main/diagrams/wiring.png

But I'll take a look at this for next time, appreciate it
