We have some farmers in our pool that also used to switch off completely during hot days. The hassle of shutting on and off, and then waiting some more for the blockchain to sync felt not worth it to some.
About a month ago, we introduced our SpaceFarmer Community Node, which allows you to farm through a remote node with instant sync.
It was originally designed for solar farmers and small farmers, but it also works well for those farmers that want to farm only during the cooler nights, and shut down during hot days. We even have a 1PB+ farmer who fully automated the process of keeping his room temperature under 30C using smart switches and Home Assistant.
Maybe this solution may work for you, too?
