I have thousands of surpluses ETL and FCC certified in Retail packed dimmers. I will make them available to Home Assistant Community at cost.
But I need help with software to port to Home Assistant, they are based on ESP32 dual-core.
If you are interested in this, send me your contact info, I will ship couple of samples.
These dimmers work with native software and app at this time using touch. Multi dimmer has screen and can control serveral other installed dimmers at home similar to noon.
