Sonoff T1 and RF433

[Richie1972]

Hi,
I've been hunting around and not found much info on this, so hoping someone can help.
Can the Sonoff T1 (3-gang) be successfully flashed with ESPEasy?
If so, can RF433 devices still be paired to them? I'm assuming these Sonoff units have a separate RF433 chip with outputs effectively hooked to the touch inputs

Any tutorials/blogs or other help on this is much appreciated.

Thanks,
Richie
