What kind of aquarium controller are you using? For example, if you have an Apex, you can run a long AquaBus cable to a remote EB4 near your chiller to control its outlet while basing the programming on the temperature probe in your sump.
My apologies for not being clear, but my chiller is located in a location that has no way to connect any physical cable (no matter the length). On/off transmission must be wireless (e.g. X10, RF, WiFi). Is there any controllers that do this nowadays?
If you're just going to turn it on and off manually, then any smart outlet with Alexa, Google Home or iOS connectivity will work. But if you need it to be controlled by an Apex, GHL or other controller than like mentioned above you need to run a long cable to said powerbar. At least I don't know of any powerbar that it's capable of wireless control from Apex or GHL.
