I don't think there's a D1-ESP32 board? The D1 Mini is Wemos' ESP8266 board. They do have ESP32 boards with the same footprint, but those are not D1 Mini but S2 Mini, S3 Mini and C3 Mini, depending on whether it's ESP32-S2/-S3/-C3.

That's what I thought as well, it is not available at:

But the specific board from the post can be bought on Amazon:

You'll find many varieties of boards with different SoCs being sold mentioning the D1 Mini in their model number or product description, as it initially defined the form-factor being referred to. Similar to the ESP-12F, which you can also get with ESP32 SoCs, if you want, even though the ESP-12F originally is an ESP8266 board.

24V AC to me seems like a strange choice when using DC-DC power supplies allows for using any external adapter, including USB PD, without the need for a loose transformer.

24 VAC is a common voltage for irrigation control, which is likely why they chose to use it.

Agreed and it’s far easier to turn ac into dc than the other way around
