Have a bunch of KAUF Smart Bulbs that come pre-flashed with ESPHome
Also have a bunch of SonOff S31’s and a bunch of Treatlife 3-way in-wall switches running ESPHome, but those both all required opening them up and making jigs to reflash them over to ESPHome from the stock firmwares.
(Edit: Plus a ton of custom ESPHome boards and piles-o-wires running ESPHome)
This is pretty much exactly what I did, started HRT, let it cook for about 8 months, and them was able to transition socially in a much more ‘flip the switch kind of way’.
Most of my dysphoria was hormonal though, I did not like the way T made me feel at all. The social aspect was less immediately urgent for me personally, but that may not be true for everyone.
Bonus info: Calvin Klein sells a no-show sports bra that does a very good job of hiding breast development for a while under even a fitted T-shirt. It has enough padding to hide pokies and protect from bumping against stuff early on, saving a lot of pain and trouble.
