Turning your fridge off for an hour will not cause your food to spoil. You probably won't even notice a difference since they are well insulated. Turning off the compressor during the hour where most of everyone gets home and turns on their AC can have a noticeable effect on grid stability if done widely enough. I do this with a smart switch connected to my HA server instead of using cloud based connections, but the effect is the same and I've never had my food spoil because of it.
