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

    I certainly see 0 in the P tuning phase. But when I add in I and D it never seems to quite get there. Could it be that anything less than 50% turns on the fan at 100% and anything over 50 turns it off? Using Zeigler-Nichols method tonight I have gotten to where I am happy enough with my...

    AMNS made more "amazen" for MES 30

    Monoprice mini is sub $200. Amazing machine.

    I guess they can't hurt... the heater meter is made to turn a variable speed fan up and down, so it really is different than many other PID. Tall, what does the output on your HM look like when you are smoking? I thought the percentage output would just go back and forth between 0 and 100, but...

    Yeah I need to work it out. My temp shot over 300' last night. I'm not sure when the therm protection switch is supposed to kick in but I just opened the door first. I was thinking of following Bryans method here...

    Eat the birds... that's funny. I agree, the last time I had this much fun was when I got my first 3d printer... but I couldn't eat the products of that endeavor...

    4 hour chicken breast smoke... Meat is done but I think I'll let the pellets continue on for testing purposes. Wood feeder is half way out and air flow seems perfect for the front row.

    Could you share some details with me about how you went about tuning your PID? My overshoots are crazy high! (BUT doesn't that chicken look great?)

    Naw... your box rox! Own it, and love it! I would imagine you could use the blower control on the HM to control your variable speed convection fan. It would be pretty simply to use another pin to control your relay, and would only take a few changes in the source code...

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

    I am designing a new case that will fit atop the MES and mount on just like the stock one. It is going to cover up both the power port and the rj45 port on the left hand side and the cable will exit the bottom. The right side ports will be open for the probes. In theory it would be pretty...

    Yeah, I realize now that there are several parts of the HM board that you don't even need to populate for an MES, but who knows when it will be used for another type of smoker that will require them. After about an hour I increased the temp up to 240. Overshot again but not as much. I agree...

    Pretty stoked right now! HM is running entirely off of the 5V supplied by the MES. I used your PID settings and set the temp to 230. I got a little freaked out when it initially shot up to 275' and was ready to abort but then it brought itself back down and has been holding steady. At least...

    No I have no plans to touch the limit switch. If it ain't broke... As far as I can tell, most PID mods are bypassing the switch entirely. By using the stock wiring and controlling the heating element in the same manner as the stock controller, the innate safety features should remain intact...

    It seems to be working well, the output is 3.3V when trying to raise the pit temp, and 0V when it reaches the correct temperature. I'll attach it to the smoker for final testing before I internalize the 12V transformer and 3D print a case.

    I soldered up my heater meter this weekend. I added a 3.3V voltage regulator to the blower output and connected the Vout to pin 2 on the rj45 jack. That way if I want to use the blower in the future it remains untouched on its native pin. The MES relay will be attached to ground and my pin 2.

    Good price on MES 40"

    How about $45? Put your zip code into brick seek and you might win the lotto! https://brickseek.com/walmart-inventory-checker?sku=169848170 ie: SLC (84112) has several stores with the $45 price. Call the store and ask them to check if they actually have it on the shelf or not.
