I might. Using the standard probes in my electric smoker has proven more difficult than I thought it would be.

Sorry Neil, I can't really recommend any brands or models, I've just seen some cards that worked fine on a PC but not well on the RasPi. The RasPi SD connector has cracked a couple of my cards to because of the way the connector firmly makes contact on the bottom but is unsupported on top...

Dan, do you have any anti virus/malware apps installed? If so, try temporarily disabling them just to test.

A couple of the most common things to check are the SD Card, both what card you use and making sure it seats properly and isn't warped, and try swapping the power supplies.

Weird, Firefox and Chrome work fine for me on 8.1.

Update. I've got my electric working much better by relocating the pit probe farther away from the element. Where is still a temperature delta between that probe and the other 3 which I have placed in various locations for testing. Right now I'm using an offset to correct this but it's a...

Thanks Colin and Uipko! My connection problems are resolved. Again, how does one buy you guys a beverage?

Would it simplify to remove 2.2 support? Does anyone still run android that old?

Thanks Matt, good idea, I'm sure it would help but I think the bigger issue is with the 10% steps and the time it takes to make heat. Say we're at 31% and there is a temp drop, HM says ok, lets start to increase so I'll go to 32 then 33, then 34, then 35, etc. By the time it gets to 40 where...

If min and max are set to 100, the blower will cycle on or off over a 10 second cycle as opposed to variable speed. For example, if the blower is at 50%, it will be on for 5 seconds on full then off for 5 seconds.

I have this working but getting a stable temp has proven illusive. I'm thinking it just takes so long for the heat to affect the internal temp and by the time HM shuts off the element, there's already too much heat generated. The blower output looks like a really sharp sawtooth oscillating...

Thanks Colin! How could one buy you guys a beverage?

I'm having the same issues running v1.2 on 4.3 jellybean on Nexus 4. The app runs ok but it's like the network connection is intermittent. I usually get dashes and if I try to run the app enough times eventually it will connect and run for a while, then stop updating.

Stan, I got everything pit all together and think I understand why I was having some issues. I now have a much better temperature range but am having overshoot issues. Do you mind sharing what PID values you are using?

I used a different jack that has an end stop inside so you can't push it in too far.

Or, I could do 4, 2 in parallel in series with 2 more in parallel, that should get a more even sampling. Anyone have thoughts as to why this would not work?

Thanks Bryan, what i was suggesting is not 2 actual inputs but 2 probes in parallel on one input with different parameters to compensate for the difference in resistance. It was just an idea spawned by trying to find a decent place to mount the pit probe in this electric and get a half way...

Ok, after testing today, It was not related to firmware, it appears to be the power supply. When I use a small digital power supply I have the issue but if I go back to a good old transformer the probes work again.

Has anyone considered running multiple pit probes? Would it be possible to run 2 in parallel and just use different parameters?

After having a bad time and having the food come out hours late I have decided to replace the cheap mechanical temp control in my electric smoker with HM. Bryan, the PWM output that drive the blower will in my case drive an SSR. I looked to see if i could find some info on this as I vaguely...
