Hi there !
Did you see this tweet ?
It would be interesting to look at…
On these links :
there are all the information to understand how the frame are built…
The main issue is how to convert hex data frame to FZ IR file format (with timings on off)
I’ve started to work on but no success…
I was just looking into this. I used furrtek’s img2dm.py’s debug function to dump to a text file

(Three of the “frames” from “frames.txt”)
I found this
I got excited because these to libraries merged together should work but I’m not skilled enough at python to make the jump. I adapted the frames into the LEGO_RCX.json format provided and used convert.py and piped to a file called esl2.ir

(Potion of the script linked below)
Flipper won’t run it. not sure if it’s too long or too big of a string. Maybe the frequency or duty_cycle is off?
esl2.ir (26.6 KB)
When I press it, nothing happens on the ESL and the flipper jumps back to the main Saved Remotes screen.
Dug around in the flipper zero firmware and under infrared_cli.c, it mentions only supporting 512 samples and some of my lines are many over that.
This post looks promising, maybe I just try send the raw hex codes
Edit: Going to stop using the forum as a blog, opened a repo
Any update on this? I have a pricer model SmartTAG HD 150 if you need help with testing.
Not really, but on the unofficial FZ discord there are much more people interested in, so I advise you to come to the Discord (if you have) 
Following this- I also have a pricer ESL I’ve been wanting to mess around with and I’ve been trying to follow this project around for a while. Seems like people are really close to figuring it out!
Has there been progress with these?
TIA
It looks like someone is working on this, but the last commit was from August 2023:
