ESP32 relay combo boards

I'm building an irrigation controller based on ESPHome Sprinkler, and rather than going the common route of esp32 dev board + multi-relay board + power supply(s), I was thinking of using one of these esp32 relay combo boards. It has AC and DC power options, an esp32-WROOM-32E module, and 4 relays. Pretty much everything I need, except for maybe a 24vAC -> 5vDC converter, which I would need anyway.

I'm wondering what people's experiences are with these combo boards. Any downsides or hidden gotchas? Will they take ESPHome just as well as a typical esp32 dev board (I've used the DOIT esp32 devkt v1 boards for tinkering and development)?
