HBN Outdoor Timer Outlet Waterproof, 24 Hour Mechanical Light Timers for Electrical Outlets Outdoor Weatherproof, 2 Grounded Outlets for Christmas Lights, Holiday Decorations, 15A 1/2HP

I've been using an identical model of that oven along with this temperature controller. No PID mod necessary. You'll have to nail down exactly where you need the knob to be to maintain the temp you want without getting too hot too quickly. I also have an outlet timer on it, so I can run it for 12 hours or whatever and it'll shut off on its own Temperature controller with probe https://a.co/d/02jx4iVN Mechanical outlet timer https://a.co/d/0hO3jFnA
