Brian, I know this something that is not normally done with analog amps, but since we really are looking at a mv level change from the thermocouple, have you tried a .01uf cap across output to ground. I know this is not a standard practice, but if noise is amp generated, it should decouple noise...

Brian, I saw the line coming out of the chip and thought that was the ref input when looking at schematic. Did you attach wire to pcb and connect it it Pi ground and then to the 12v ground to see if the shield grounding would make difference. Other than that, Sounds like if you want lower noise...

Brian, Looking at the data sheet I see that they recommend a 10uf cap in parallel with the .1 uf cap on the VS+/- chip supply. I see down in the data sheet that this can be a shared cap. They still look like they recommend it to be located closed to the chip. Also they show the Reference pin...

Brian, For me I see no difference between the 2.4 and 5Ghz readings on the noise graph. This graph was made using a corded power source instead of the usual battery setup since digging battery out of garage right now is not safe. The last graphs I posted were made with same corded power source...

didn`t hook scope up since it is in the shop that got flattened last week from a wind storm, but here is my noise graph from heatmeter. Now on 5ghz radio. Thermocouple is shown. Graph looks the same whether I am using 2.4 ghz or 5 ghz radio. Also doing this in office where I am 4' from router...

I wonder if the power output is higher with the 2.4ghz band. Granted the 2.4ghz band has better transmission than the 5ghz band. Also I have not looked, but I wonder if the bandwidth of the 2.4ghz could cause issues. My router selects 20, 40 mhz i believe. Would have to logon to see if it goes...

I have not had good luck using aluminum foil for rf shields but that does not mean it does not work. I usually use copper foil. But besides that, have you tried the same test and observations using the original Pi3. That processor was clocked at 1.2 ghz versus the 3+ at 1.4ghz. I am curious if...

If a RF cage around thermocouple amp might be a tough design, maybe changing the RC on the amp input to limit signals from DC to up to 37.5 hz might offer a solution. We don`t need the wider bandwidth, only mv changes from the welded junction. Sometimes we can mask signals we do not want by...

I am wondering if what I experienced was similar to what you experienced. Brian, Went ahead and updated to your current snapshot. Just found a good one for you to try. Go into your config screen page. Make sure you have a damper connected and your heatermeter setup with a thermocouple. Now...

Brian, Here is yesterdays cook of some pork tenderloins. From the graph, the first lid open event occurred when I reached 225 , setpoint, and it looks like lid tracker kicked in and made corrections. I then waited for about 5 minutes for temp to stabilize and then opened lid and added the...

Darren I agree. I always remove my damper and then use the silicone plug to close off adapter that the damper connects too.

I wish I could say that every situation you brought up was my issue. Been using the hm for a few years now and I have my settings dialed in and know how my grill works. I am very careful when I light my lump and in the case of my last cook, coals still had 4-5 hrs left and they burned evenly and...

Marc I have a Primo jr and I am including my settings config page. I also use an Adapt-A-Damper. I also run my HM with a battery to reduce issues with noisy power sources. Currently using threshold method of lid control. Using lid tracker with current configuration causes control instabilities...

ran into this issue before Christmas. My snapshot somehow wrote to a different partition than normal. The only way out for me was to go to disk management in Windows and delete all partitions on the sd card there. After that I formatted using SD Formatter and then installed image and everything...

Brian, Thanks for getting back on this. I myself could not see any problems/differences with wifi config file for both versions of the snapshots I compared. Nothing made sense. Both routers were up and running. Both radios were bands on both routers were working and the devices around the house...

Brian, Ran into an issue on Xmas while trying to BBQ a roast. I could not connect to my network. I usually do not have any issues with this, but since updating to that latest snapshot I cannot connect. So right now I decided to see if this was an elf playing games or a real bug. It`s real, not...

Does this include grillers in legal states? Merry Christmas everyone out there.

Could be a pulse of some kind. When I set the heatermeter up at the grill, I never see this spike and control manipulation. The only time I see jumps are when I log in or out of the config page. These are small and really do not bother me. I will be using latest snapshot when I cook on Xmas...

Exactly. The output and fan change. I have a video of this and you can see the damper open and hear the fan change. The heatermeter displays the output going from like 50% up to 85%. Love to figure out a way to send the video to you. 12.5meg I have noticed this back in another snapshot from I...

Brian, Went ahead and updated to your current snapshot. Just found a good one for you to try. Go into your config screen page. Make sure you have a damper connected and your heatermeter setup with a thermocouple. Now turn heatermeter to on and lets set it to 60-70 degrees at the heatermeter. I...
