Brian Is there a way to scale the output opening and closing like we can with the fan. Example would be with my Adapt-a-Damper. At 100% output I would like the damper to open 50%. I can do that by adjusting the servo pulse duration, but would be nice to just have those fixed at full range...

first question is which damper are you using. Next where are you placing the pit probe in the grill and is it a thermocouple or rtd. What brand of device is the pit probe. Last, where are you place the pit probe. I do not mount mine to the grill, instead mine is real close to the grills...

I think that you should do you fine tuning with product in grill. But if your going to make big changes I would load something in there that you can cook low and slow to give you time to tune. Make sure you let the grill adjust at least 15 minutes between tweaks. I always have a mix of fresh and...

I do not use the 4.2 controller by I do use the 4.3. I see that you use a UDS. If it is air tight and well insulated, then what is what I am noticing is the "P" setting set to high. Controls break into oscillation and now you get frustrated chasing the PID dragon. Here are that settings I use on...

Like Will said, ceramic grills and other like the big boy he built out of steel are well insulated and have excellent sealing materials on gaps and between shell half's. I use a Primo Jr. and I suspect if I used the original design of the heatermeter 4.2 with the blower, my grill would work...

had bad case of flue past few days so my last post was pretty bad. Anyway From the description you put out, that is the Tom Cole design I use and when it gets used, I must go into the configuration screen and reverse the servo`s output direction. The setting is called "invert Output". Since this...

here is a link to a jack wiring that Will Begg has done https://tvwbb.com/showthread.php?63198-The-Adapt-a-Damper-Open-Source-Project/page23 you have picked a very good damper. I use the Tom Design you chosen and Will Begg`s Adapt-a-damper. I have built and tried the other tom Cole design and...

I going to chime in here with my opinion and ideas on this heatermeter use. First off I believe you will need two SSR`s. Also be aware that SSR`s can be tricky to use since they are solid state devices and the switched output connection is a semiconductive junction. That means some SSR`s can...

another question for Dusty is, did you test the HM prior to installing in case. If it worked prior to case install, you likely bent the leads of Q1 when you installed into case. That is how I shorted my Q1 when I did my build. What I did when I installed Q1 again, was to shorten the leads and...

try this for a test. plug the thermocouple into the board. measure between shield and one leg of the thermocouple on the board. It should read greater than 10 megs. The higher the better. Do this for the other lead to shield. measure across the thermocouple leads on the board. should measure 0...

since you have a connector on the thermocouple sensor, just disassemble and make sure the connections are good and where they strip the outer jacket back, they did not damage the insulation on the thermocouple leads where the shield stops and the couple leads emerge. I have had to carefully...

the Cabela`s has an option that includes a charger for $29. Battery alone is $20. I went to Walmart and got a Deltran Battery Tender Junior. It is an automatic charger for 12 sealed ,AGM, and Gel batteries. Comes with all the cables and connectors you will ever need. $30 at Walmart and I have...

I use battery power as well. I use a sealed battery from Cabela`s and quick a disconnect for cigarette lighter adapter. I use another plug that mates to the cigarette adapter and proper cable and plug to match heatermeter. I get 20+ hours and never have issues with background noise or noise from...

If your damper door is removable, then make a new door and go to an electrical supply or your local Lowe`s or Home Depot or Ace and get a small piece of 1" emt conduit and a couple of compression fittings. Drill hole in your new plate you can make from scape steel or a piece you can get from...

it looks like to me that you have too much "P" and "I". Since this is a ceramic grill, make sure it is sealed tight. Now smoke leaking out dome gasket and gasket that seals the main grill cover to base. try these settings if you want. These are for a Adapt- A -Damper. Should be good starting...

I have experienced the Q1 issue and I caused the problem. If your not careful when installing the boards into the case, Q1 can be twisted and even destroyed by forcing boards into a tight tolerance case. I am sure lots of the Q1 issues are them same as I experienced.

since your using a ceramic grill, the pid numbers for most of the ceramic grills out there will have close, if not the same numbers, for any ceramic grill. The P value should be somewhere around 2.5. I, should be somewhere around .0035. Anything higher will make the oscillation from the high...

Brian, I am back up and running. How I originally tried to update was from the download page. I selected the snapshot and made sure it was for my Pi and HM combo. I next went down and setup the wifi connect area and them got my download. It was and image that also had as part of the name my...

Brian, went ahead and updated to new snapshot. Unit says it updated correctly, but the screen went blank and never came back when power was cycled. I took HM apart and checked the sd card and that looked good. Even formatted and reflashed with same results No HM. Tested the PI and it worked...

did you swap the 100k and 10k resistors for probe 1 on the circuit board?
