I've seen a couple recommendations to go HomeAssisstant. I agree completely, even with the caveat that there's some work in that. That said, I'm in year 7 with HomeAssisstant, and don't see other options that are as capable.
Similarly, Tasmota and ESP Home are high on my list of preferred firmwares. If I can Run a device on either of those, or even better, if they come with one of those firmwares pre-installed, that's a win. Shelly is mostly a win, and they're enough of a win that I reommend their stuff without much or any reservation. Tuya can absolutely go screw themselves with a rusty wire brush.
Companies that violate their agreements like Futurhome need to run into the ground and their owners made permanently, personally bankrupt. IANAL, but the words "class action" seem to fit this scenario. There's definitely harm and numerosity.
