There is a community integration for Blink cameras:
I just looked on the Hubitat Compatible Device list and didn't see any mention of BSEED or Aqualisa unfortunately:
Often devices that are Wifi rely on their manufacturer's website so are not able to be used fully local which is against Hubitat's model. Therefore, there are only a few Wifi devices that work and many that do use drivers/apps that were created by the community members through back doors.
I Googled and it looks like Home Assistant was able to work with the BSEED lights using their Tuya integration. There is a Hubitat Tuya Community Integration but I don't use it and know nothing about it. Hopefully, someone else can comment on that.
Somebody outside of the Hubitat community is working on using MQTT & Homebridge with the Aqualisa shower:
I know nothing about this other than reading the 1st few posts.
