Hallo, I wanted to share my ESPHome custom light project to control my Hamulight LED spots. These spots came with the garden room and use a proprietary protocol. So I had to reverse engineer the signal from the remote. I did this using a software defined radio and Universal Radio Hacker software. …

Hi, Is this project still ongoing and have the others this working. I’m having also a Hamulight L2046 but could not get it work. I read in the manual of the controller that you have to pair it. Below link is from official website. https://www.hamulight.com/nl/mst_attachment/attachment/click/atta…

Hi W I read the link to the manual you provide. It looks like the same remote. I never paired it, but maybe the installers did this. This could explain why the project is not working for everyone. Some part of the RF signal could be a code/number created during pairing.

Someone else having the L2446 remote?

Yes I recently got the L2446 remote. I used my RTL-SDR to find that it appears to be using FSK (frequency shift keying) so I ordered a transmitter on Aliexpress. I’ll post an update here soon.

I am also interested in a solution for this as I have the Apex L2446 remote. HP

I opened the remote and it contains a BS84B08C microcontroller and a BC2102 capable to OOK/FSK transmitting. My Boardlink RM pro seems not able to handle that. I am uncertain about the connectors. [HAMULIGHT] Maybe it’s worth to connect it to an ESP8266 like done with the Somfyduino project. HP …

Hi, I have also have the L2446 remote for Hamulight. Trying to receive the signal using a Sonoff RF bridge flashed with esphome and the passthrough firmware of the radio chip by Mightymos. However I do not receive anything from the remote, even with dump set to raw I find nothing in the log files. A…

Found out that my radio chip flash was bad. The red light on the RFbridge is supposed to be active after boot, just is the blue one for the WiFi. The receiving part works, now looking for the messages from the remote.

today i published an info website about my knowledge of Hamulight L2046 remote controller copy. [image] Electronic projects
