Would 24v damage the nest hello? it only need 18v, not 24v.

I been using it for around 3 months with no issues with the Nest Hello.

Does this work with Nest Hello?

Yes it does work with the nest, I'm using it with mine and a pellet stove

The “ul” label is no longer included on the unit. is the unit being shipped longer ul certified?

I really wish people would just not respond if they don't know the answer... Anyway, I just moved and dug my Ring doorbell out of a box along with this transformer. When I installed it, I included a huge 250 Ohm resister for some reason, got the recommendation online. Regardless, the Ring was not charging, so I tested the voltage from the transformer and got 25 volts consistently, not the 24 volts it claims, and not the 8-24 volts my door bell wanted. Sure, I got an extra volt for free, but I don't know what that will do to electronics without knowing what kind of regulator they are using, if any. So, since it provides more voltage than stated, it might not be approved anymore - I don't know. I bought this in late 2019.

Will this work with the vine 610 thermostat

This will work with any thermostat. It simply provides the 24V power needed assuming your tstat wire and doesn’t have the additional wires for 24v power. Most furnaces have the 120/24V transformer, but older homes tstat wire never had enough conductors. Newer homes should. Regardless, yes, this transformer with work.
