i was able to make a white LED aquarium light (Dennerle Nano-Power LED 5) smart via H801 running Tasmota. No big deal, only programming a sunrise / fall via rules is rather cryptic.
for my new tank i got a Chihiros RGBW LED light with a cloudbased bluetooth controller. It would be nice to hack the controller or use the H801.
Does anybody have any experience with Chihiros to share?
You got a link to that device?
My devices still to be smartified are:
The light:
Included Controller:
Or do you mean the H801? This is very common:

The Chihiros wifi bridge has a UART port on it. It’s custom board with an esp07 controller. I’ve been tinkering trying to dump the console.
Not the greatest pictures, but this is the board design. the chip in the bottom right has some numbers written in pencil but I can’t identify the chip. I would assume it should be fairly simple to integrate since it’s already based on an ESP.

i think one needs to decrypt the bluetooth commands used.
the esp here is just a wifi to ble gateway.
any update?
Hi,
I have a couple of Chihiros lights as well. I had purchased the Wifi bridge also. When it work, it was fine, but was not very durable. I went thru 2 of them in about 9 months. They just died and I couldn’t reset them,
Like you I started searching and I found this https://github.com/TheMicDiet/chihiros-led-control. and it works great. You can control the lights thru HA easily.
I used as ESP32 with ESPhome to create a bluetooth proxy and it has worked flawlessly. https://esphome.io/projects/?type=bluetooth.
I’m working on using Ashely’s Light Fader to do ramp up/ramp downs. I think it should work out great.
Check it out!
cool. thanks for the info.
will have to dive into esphome first.
Creating the bluetooth proxy in esphome is really quick and easy on the link I included.
Install Esphome then goto the link.
Just attach the esp32 to your computer with a USB cable and follow the directions. You will be asked for your wifi credentials and your done.
Probably took me longer to write this than it takes.
Good luck.
Created the proxy and after some time (no BT feedback at proxy visibel) the bluetooth LED control got recognized.
I still have to figure out how to use, as in HA there are only sliders for color.
I dont want to rely on realtime HA automation so it would be ace to be able to program a light schedlue on the device, as with the app.
