I run my Tuya switches locally on HA - no need to update firmware. however I don't believe it would be possible on Hubitat as there is still no UDP support available.. 
It's a surprising omission for a company touting a local solution.

There’s been UDP for a few years. I’ve got three or four drivers that use it.
Really - you can listen for a UDP datagram - keeping the socket open permanently - and receive broadcast UDP ? I knew you could send a UDP datagram and process an immediate return but nothing beyond that.
@gopher.ny Is there persistent UDP support? Can’t remember if you can leave it open without checking my drivers.
You can return a HubAction with options containing type: 'LAN_TYPE_UDPCLIENT', and the hub will send a UDP packet. A response, if any, will appear as a callback to parse method.
There is no listening on the port without sending something first at the moment, though.
What's the use scenario?
@kevin would have to tell you the use-case. I’ve always just polled UDP devices for state changes, which has been working great for a few years now.
It is for any use case where a device pushes out a UDP packet - typically broadcast for status events. Quite a lot of devices actually do this. Because they are unsolicited and sporadic HE can’t receive them.
Tuya switches do this I believe when switched so tracking status requires it.
