      Weird, what I hear you saying is you don't need all the features that PID offers, peace, but for 95 bucks it does everything you want, has a PC interface and you don't drop down a rabbit of hole of making your own. It has alarm outputs iirc which you could do something with - bang a gong say lol. (I like the idea of loud large gong noises as alarms). Your situation of course, just saying they are a low cost effective solution

        As I said earlier, pretty hard to beat the price and flexibility of a Pi and there are many routes to achieve the OP's purpose with one.

Just awful that in this era you're expected key in so many different fields and info from a few stupid little buttons while trying follow those miserable instructions that are near impossible to understand for a beginner.

          I put one in that has a USB connection and use software to program the PID. Its about the shlttiest bit of software ever written (really really bad) but entry via laptop is a quantum leap forward from the PID user interface. It lets you type out in a table form the different segments of a cycle as well as query and display whats in the PID. Big improvement, but it does stupid stuff. Like you set R1 to 60 minutes, write it to the pid, then query the pid and it shows 6 min. In the query screen, you change it to 60, but its really now 600. Stupid crap like that that makes consider the program a real POS.

          A well done phone application, showing the ramps on chart that you could click on and change is how it could and should be, but the above on the laptop is a step in the right direction. You've got a serial connection on the PID and blue tooth modules are available for Arduino....but what do you to for the program on the phone? That's I think where the heavy lifting is .
          I have a Novus N480D controller, which has a USB interface, looks very similar to yours, Mcgyver: https://www.automation24.com/pid-tem...usb-80480d2080

          Does everything I've asked it to do. The manual, while very technical, is written in clear and concise english. I'm not sure why I'd need to have a wifi or bluetooth interface to it, but I'm sure it could be, and probably has been done.

            Wash, rinse, and try again.

            I have a PID temperate controller which in the common vernacular gets shorted to PID.
            If you ask a supplier for "a PID" they're response will be "WHAT?" or some variation. Using it that way is just unnecessary jargon and nothing more. People here, there, and most places call a temperature controller with PID a temperature controller. There's no point in using vague technical terms. As I said it makes no more sense to use it here that it does to refer to your household oven or your car's fuel injection pump as "a PID".

            Weird, what I hear you saying is you don't need all the features that PID offers, peace, but for 95 bucks it does everything you want, has a PC interface and you don't drop down a rabbit of hole of making your own.

            It would be weird if I had said that but that's not at all what I said. I said the profiles that I use are simple enough that I don't need the ability to store them. I didn't mention anything about not using the PID functionality which can be used independently of a multi-step temperature profile or the ability to store and retrieve profiles. And by the way, you don't program "the PID" any more than you program Windows when you click on a desktop icon on enter a file name on a DOS command line. I do agree that it has a lot of features for the price.

                  About the same time as you in 2012 I set up my heat treat oven with a PID controller, SSD relay, etc. I used an Omega CN7823. It comes with downloadable software for a PC. No programming you just set everything up, ramp times, temps etc. you can save a configuration for later use ie anneal, heat treat A2 etc. Real easy to use. I got a matching K probe with custom length for my oven. I put everything in a box so I just plug in the oven. Made it separate so I could use it on any oven. Here is example of setup for anneal, the heat treat oven is just set to high which bypasses its internal temp control:
