Question: How to make a template that let me see what the first next timestamp is?
I have 3 sensor timestamps:
sensor.rova_bio _ status: 2023-01-09T23:00:00+00:00
sensor.rova_paper _ status: 2023-01-29T23:00:00+00:00
sensor.rova_plastic _ status: 2023-01-22T23:00:00+00:00
How to make a sensor that is telling me the first next of these tree?
