Request recommendation: temp controlled teapot

Hello, as the title implies, I am looking for a temp controlled teapot.

I own an ember mug and have to say, it is one of my favorite purchases/splurges. For those that do not want to click on the link, this is a temperature controlled mug that holds a hot temp for liquids in a mug wirelessly. It does this with quite good precision IMO, have not whipped out a thermometer to check accuracy.

I have been looking for some time for a teapot that could do the same. The requirements I have are that no plastic or otherwise health adverse heat volatile materials come into contact with the heated water, and I would like it to be a teapot, because I like the ritual of pouring the tea out of the pot. I want to be able to steep and pour the tea from the same temp controlled vessel(I don't mind heating water and then pouring it into the temp controlled teapot), so I'm not looking for a temp controlled kettle, necessarily.

I think last time I looked I ended up on pages showing things like this set up, which I'm open to, but would like some guidance or reviews, if possible.

Thank you!

Bonus, what are your favorite mint teas or other teas that have a sensory experience outside of temp?
