I have flashed all the bulbs and ceiling lights in my house and they work locally on FOSS firmware now 😉 It is not a big deal. I have very poor soldering skills, and I did this anyway.
That’s what I did 🙃 Unfortunately, some devices do not work at all without a connection to the manufacturer’s cloud, this also needs to be taken into account.
