This device can currently be flashed to tasmota with Tuya-convert. The advice on blakadder.github.io/templates/qs-wifi_D01_dimmer.html was great and suggested compiling tasmota with scripting and setting up the following script to get the dimming working gist.github.com/thxthx0/c22555f6ec25c3367264729a0ff74dce#file-wifi-dimmer-script-txt Once the device is all setup correctly a command can be issued via the Tasmota console to make it appear in Home Assistant, Enables MQTT discovery: SetOption19 1 Light brightness can now be fully controlled

Home Assistant: Fix the entity IDs for zigbee2mqtt devices

Comments 1 comment

New Zigbee devices might get setup in Home Assistant before you get a chance to setup friendly names in the zigbee2mqtt config file: /home/user/docker/hassio/share/zigbee2mqtt/devices.yaml If this happens a fix is as follows: stop home assistant clear the incorrect entities from: /home/user/docker/hassio/homeassistant/.storage/core.entity_registry restart home assistant and the zigbee2mqtt devices should now be in home assistant with the correct friendly entity IDs

MicroPython & ULP/RTC Memory

MicroPython & ULP/RTC Memory

Big power advantages exist for using the ULP ( Ultra Low Power ) processor for regular tasks like recording a state change from a GPIO or ADC input, storing the information within the RTC memory, then waking the main CPU up when the information needs to be transmitted via Lora. The programming of the ULP can now be done via a simple MicroPython wrapper: github.com/ThomasWaldmann/py-esp32-ulp/ github.com/micropython/micropython/pull/3578 ULP examples github.com/espressif/esp-iot-solution/tree/master/examples/ulp_examples LoBo MicroPython for ESP32github.com/loboris/MicroPython_ESP32_psRAM_LoBo/wiki/rtcgithub.com/loboris/MicroPython_ESP32_psRAM_LoBo/wiki adds RTC.read and RTC.write NB: Still looking…
