Current hour sensor/helper

Hello all,

I run an automation which lowers my thermostats based on energy usage in our house. This is currently running 30 minutes each time it is triggered, but it is only necessary to lower the heat until a new clock hour, e.g., between 16.00-16.59, 17.00-17.59 and so forth.

The goal is to minimize our hourly peak usage while running other appliances in hour house (washing machines, dishwasher…).
