When I talk about a hario v60, I am talking about the glass or ceramic cone you put the paper filter and grounds in not the kettle.
I use a 1L electric kettle and bring to boil.
Water boils at 212 f normally, but 210 at my elevation.
I check with an instant read thermometer after about 1.5 to 2 mins off the boil, until it reads 205 f. By the time I am done with bloom and pour over it is about 195.
There are some kettles you can set temperature and maintain it but they are more expensive than I want to pay.
A little experimentation with an induction element and that manual kettle and it will hold proper temp all day. My local coffee shop ran that set up for years before they invested in some high end variable temp electric ones.
