220v relay board flashing

[pppp33]

Hello there,
I am looking for a small, single channel relay board, possibly self-powered.
On Aliexpress i found this one:

Now, the questions:
1. Did somebody in our community successfully flash and use it in some project ?
If yes, can you share pinout ?

2. Since it will work at 220 Vac, What about design and quality ?

Thanx in advance & Regards
Paolo

Don't know this board, but why not "just" a Sonoff? Well proven and inexpensive.

Actually I need to switch a 24 Vac solenoid valve, so I need: 220 Vac power (for esp board) and dry contact from the relay to switch 24Vac.
Which Sonoff module does this ?
Thx
Paolo

This runs on 5-24V input voltage, no need for 230V: https://www.itead.cc/sonoff-sv.html
