    Successful MES brain transplant! Plug and Play replacement controller = Full PID + Cellular contro

    Based on what I learned from a power board that mates with a 4 pin controller the pin ordering is the same minus the light signal. This could mean the actual pin numbers are renumbered from my 5 pin controller. Regardless, here are how the pins are labeled and ordered on the power board: Power...

    Successful MES brain transplant! Plug and Play replacement controller = Full PID + Cellular contro

    I am really thinking about putting together an Arduino controller or following Tiros Esp8266 micro controller setup. I've also thought about looking into a PID (Inkbird on Amazon?) that would work with the built in Power Board. But, if it takes circuitry to make it work with everything then I...

    I probably didn't state things as clearly as I should have, but mainly wanted to correct my post so I don't trip someone in the future.

    HeaterMeter Controller, with Wifi, and Electric Smoker (MES40) Mod in Detail

    So just the Esp8266 as the brains? I'm just reading up on Arduino controllers. Sounds like one (Uno?) might be necessary to program the Esp8266, but from your post and pic the Esp8266 is all you need with some logic, power, and protection around it.

    Successful MES brain transplant! Plug and Play replacement controller = Full PID + Cellular contro

    Quick update. Based on MM2021s work, my earlier post is not accurate at least for his unit which I believe is very close to mine except no light in his model. So, in this case the thermostat must be wired inline to the AC line running to the heating element. I don't recall why but originally...

    Successful MES brain transplant! Plug and Play replacement controller = Full PID + Cellular contro

    Interesting. I'll have to look at the info I captured for my smoker to see if I can figure out where the back wall temp sensor is tied in. With you confirming the 2 wire is the meat probe then STOVE-T would have to be the input to the controller, right? Hmm. This would also mean that my...

    Successful MES brain transplant! Plug and Play replacement controller = Full PID + Cellular contro

    MM2021, Ah, so the light is the missing line. Yes, STOVE-T is the label on the Power Board (see one of my post above for pic) that runs through out and through the high temp cut-off. I've had both the Power Board and Controller on the bench to troubleshoot. It's a 5V signal that is sent through...

    Successful MES brain transplant! Plug and Play replacement controller = Full PID + Cellular contro

    Very doable. See my previous post where I mention Gen 1 Power Board removal.

    Successful MES brain transplant! Plug and Play replacement controller = Full PID + Cellular contro

    Kurt, You are correct that the Gen 1 Power Board in the bottom is really meant to be permanent with rivets holding the cover in place. My Power Board failed shorted and pushed the smoker to over 300 deg F before I realized it. I drilled the rivets, cut through the white rubber type coating, and...

    Successful MES brain transplant! Plug and Play replacement controller = Full PID + Cellular contro

    MM2021, From my research I believe the 5 position connector numbering is reversed from how you've referenced them. I know it really doesn't matter for our discussion, but just wanted to be accurate to the original design in case others catch up with our dialog. If I'm right... Controller...

    Successful MES brain transplant! Plug and Play replacement controller = Full PID + Cellular contro

    I wanted to follow up with an answer for anyone following this thread. The STOVE-T has 5V applied by the power board (shown above) that then runs through the thermostat and finally routed up to the control panel where it monitors this signal for open/close. From a quick test, the control panel...

    Successful MES brain transplant! Plug and Play replacement controller = Full PID + Cellular contro

    Do you know the purpose of the black wire? I uncovered the power supply board under my smoker and found the black wire is labeled STOVE-T. Is that STOVE Thermostat or Temperature?? It is also routed to the 2 pin header that's next to the 5 pin along with +5V.

    MES 40 Rack Supports

    Tiros, I believe I might have the same 40" 1200W MES (gen 1, I think). Just picked it up and had to do some work to get running. I've smoked a couple of things that turned out great. Sounds like I will have to be careful how much I smoke at once. Really seems the 40" space is unusable. Any...
