My apologies, I didn’t know of that implementation of HASP. Interesting…
I guess it will depend if the display in the lanbon is supported in hasp-lvgl.
Hi there, openHASP indeed runs on that switch! blakadder recently published a review of some alternate firmwares for the Lanbon L8, including hasp-lvgl.
We have now published a .bin for it to test, but not all features are supported yet. HA integration is still being worked on, etc… Check out the hasp-docs for more info on the project or feel free to join our Discord channel.

Can setup with Tasmota:

There is a review here https://blakadder.com/lanbon-L8/ and reviews of alternate firmware here https://blakadder.com/lanbon-L8-custom-firmware/

Bought one, super happy! well build, looks nice on the wall 
Actually ended up using https://fvanroie.github.io/hasp-docs/# instead of Tasmota.
I also created https://github.com/dgomes/hasp-lvgl to easily integrate with HA

Thanks for posting an actual picture of the switch on the wall. Gives a nice impression of how it looks like.
I have a couple of questions on the build quality, if you don’t mind. It’s probably due to the perspective of the photo, but it looks like the screen is not perfectly aligned with the frame, like if there is a slight rotation. Do you observe that in reality too ?
It also looks like the screen itself is slightly recessed behind the transparent front plate ? I assume this is what creates the black borders around it ?
And finally, what is your impression of the screen quality itself, in terms of contrast, sharpness, etc. Does it look high end, or more like a flip phone screen from 15 years ago ? 
Thanks !

Well it was not a well though picture 
The frame and LCD are aligned, plastic is of high quality and you have a glass in front of it all (that’s why you have the black around, its just shadow).
it’s a basic LCD, you are not going to have pictures in it … 320x240 pixels…
ultimately, for the price of the thing, you get what you pay for, and I’m not complaining here

Great, thanks for the additional info !
Can anybody with the L8-HD dimmer version check what dimming MCU they are using?
We are trying to gather some info on dimmer device and protocol used to talk to the module.
Hi juan,
We’ve compared the PCBs and these seem to be exactly the same as the Lanbon-L8-HS switch. So the dimming occurs in the base and is controlled via the small pin-header.
We have reason to believe the communication between the ESP32 and dimming MCU is serial based but I don’t know what pins or baudrate is used. That’s the next step we’re trying to find out, either via a scope on the pins or serial UART when it’s detached from the base…
The goal is to add support for the dimmer in our custom firmware.
Where do I look for this info?
It might be difficult to access the PCB in the base without tearing-down the device. I don’t have one myself, so can’t really tell exactly where to look. Any information, pictures, etc will be helpful though.
Hey @fvanroie this page https://haswitchplate.github.io/openHASP-docs/#devices/lanbon-l8/ mentions an AU version of this switch, but I can only find US or EU. There are however US versions with 220v (they separately sell the US as 110v or 220v). Is the AU version just the US shape with 220v?
Also I can’t seem to find on Aliexpress the L8-HD (dimmer) Model Number: L8-HT (thermostat switch) L8-HB (boiler switch). Any clues ?
There is no AU version.

Thank you sir!!
I’m pretty sure there were AU models on alibaba that, indeed, seemed like the US version with 240V.
Thanks. That PCB is identical to the switch/relay version. The difference is in the PSU base, that has a pin-header connection to the panel. What we’re trying to find out is which pins do control the dimming process.
I don’t think it’s an analog pwm signal, but rather a digital serial command.
There are indeed specific 110v and 220v versions
