ESPHome

Hi Folks, Was able to get 2 of these lamps running completly local with ESPhome (LibreTiny) - No Dissasembly - No Soldering - All over the air - Never had to download or log into Tuya App. Yeah!

I pretty much followed Digiblurs guide [UPDATED How To Guide - Tuya CloudCutter with ESPHome LibreTiny - No soldering | digiblurDIY] with the following things to note:

  • Used a Rasberry Pi 4 (Tried first with Raspberry Pi 2 B, but the WiFi dongle I had couldnt get it into Access Point Mode. RP4 has inbuilt wifi and AP mode)
  • Used the Raspberry Pi Imager with the Raspberry Pi OS Lite (32-Bit)
  • When I got to the “Install ESPHome Kickstarter firmware on the Device” section, step 4, the “Manufacture/Device Name” option did not have a compatible image. So I used the “By Firmware version” process using the “2.0.0 - BK7231N / oem_bk7231n_strip_ty” version.
  • I used this firmware file selection “ESPHome-Kickstart-v23.08.29_bk7231n_app.ota.ug.bin” (not the OpenBeken firmware)
  • If you follow along closely, you will have to put the lamp into slow blink mode twice.
  • After sucessfully cut from cloud, just connected to the Kickstart access point so I could add the correct local wifi details.
  • Used the ltchiptool to generate the yaml.
  • Created new ESPhome device which I called geniolamp01 and spliced in the YAML from the ltchiptool.
  • Generated the UF2 firmware and flashed from the lamps Kickstart web site.

Problem:

  • The YAML that was created by the ltchiptool did not enable the use of the button on the top of the lamp.
  • I wanted to still be able to turn the lamp on and off from the lamp.
  • I was able to determine the pin required to enable this (Pin 14), so added additioninal information to the YAML (As well as adding all the other stuff I like to add to the YAML :slight_smile:)

For those that are interested, here is the yaml I have used:

#Beken chips, unlike ESP, do not have an RTC memory for storing data. The settings are saved in flash memory every 10 minutes, not every time you change. If you need to shorten the time, then use the code below
