I’ve always thought it is weird that the history tab isn’t filterable and searchable. To me it makes more sense to have it empty by default and select the entities I’m interested in for a specific time frame.
It would make it a great tool to debug or for instance check if it is at least slowly cooling down (my house is very well insulated and this was a question that popped up today). Any ‘one-time’ question. Right now I actually make a history-graph in a lovelace dashboard for such things and delete it again afterwards.
It would also be nice to hide it for anyone but the admin, just like dashboards.
