What about a WiFi connected smart outlet? It can be voice controlled or controlled from a phone or turned on at the outlet. You can set just a “run timer” (from the time I turn it on, run 2.5 hours) without it repeating.
AND if you need to make sure it’s off at any point, just check your phone.
TP Link Kasa outlets can run for 23 hours and 59 minutes at a time.




So everyone else has good points but there’s one other part I don’t think was mentioned.
Most ISPs use a PON based network. This lets them connect one fiber in their network and “split” that to up to 128 (or more, depends on the OEM) customers. You need a either GPON (Gigabit passive optical network) or XGS-PON (10 gigabit symmetrical passive optical network) SFP module and usually the ISP has to get a serial number off of that module to provision the proper data service.
This is contingent upon the ISP being willing to do that. The one I currently work for, we really don’t do that except for businesses.
