This looks promising… Do you know if this will be fully capable of being run without internet/cloud service? And is there a local API on the device I could use to add to my home assistant automation? Trying to find all the devices I can that have local APIs (so that I don’t have to rely on internet) to get really complex custom automation and it seems hard to find any products like that, haha
