The trafo will cost 280EUR at audioelektronik-shop.de. Just got an offer. Delivery 14days. 230V... I have found a better option https://tube-audiodesign.hpage.com/netztrafos-ac-transformers/hochvolt-transformatoren.html#top waiting for an official offer, but will be in a range of 80EUR for a 220VA RK Trafo! Will come with 115/230V primär and has ~10days delivery.

Hello, Version 1.4 is now arround and has experimental support fot the honnywhell sensor. By experimental this means, may cause the end of the world or may kill cute kittens, is not tested as we don't have the sensor in the lab. To enable the sensor you need to change a define in the firmware on top where the SDS011 is initiated.  @Jerry: Did you also Upload the Webcontent to the ESP and have you configured it for you WiFi ? If not Configured  the ESP32 shall stat the Accesspoint and from 1.3 onwards you shall see a Wifi "ESP32 Weatherstation XX:XX:XX" where the X are a part of the device MAC Address.
