Датчик CO2 за ~1400р. для HA и Zigbee2MQTT

Давно хотел в Home Assistant завести CO2 датчики, но на этапе уточнения цены душила жаба. С недавних пор увлекся поделками на ESP32, еще раз погрузился в тему с учетом новых знаний и оказалось что можно жабу не будить и сделать все не просто просто, a очень просто и не дорого. В процессе так же захотелось что бы LED на плате показывал концентрацию CO2 цветом от зеленого до красного мигающего, меняя при этом яркость, а не только отсылал данные через Zigbee Итак, нам понадобится:

Haven't heard a lot about the #esp32c5 recently. There must be some interest since Digikey and Mouser are both out of modules, chips and even the dev boards. The only thing I've seen is a board from @olimex, and at last report they don't ship to USA anymore.
