Temperature Control Devices

I currently have a Inkbird WiFi ITC-308 Digital Temperature Controller, but the heater port for it stopped working. It lasted for over a year. Turns out my heater might be a higher wattage than what it supports. It is 15,000 wattage. I’m currently looking for another device that I can use to plug my AC and heater into that supports 15,000 wattage. It would be nice if I can monitor it through a wifi app and be able to set the target temp differently between night and day. So far I’ve only been able to find these 2 items somewhat to what I am looking for. If anyone has suggestions it would be very appreciated, thank you!

I am fond of AC-infinity products.
They have designed designated systems for grow support.
