If you're using ESPhome, the BedJet addon replaces the hardware remote and app. It's kind of funny if only because the only processing inside the BedJet is..... an esp32, so you're throwing an ESP32 at another ESP32 ;)

I run my BedJet into HomeAssistant (and from there, into HomeKit) so it's so nice to ask Siri to warm up my bed now.

I found mine at a Value Village for a hundred bucks with everything but the mattress clip and remote, and BedJet support was able to just let me buy the mattress macguffin again for around $25ish.
