That die mot workshop als well. I got a new rPI today and that fixed the problem...

So the only solution would be to get a new rPI?

No luck either :(

I just checked these connections,but there is zero resistance between them.. Anything else I could check?

Thx, did that again now but noticed an error: Connecting to capnbry.net (71.100.233.140:80) hm.hex 65% |******************** | 47310 0:00:00 ETA hm.hex 100% |*******************************| 67722 0:00:00 ETA Stopping LinkMeter OK LinkMeter platform...

No they are blank. HeaterMeter Information Version 20140630B

Hi Ralph, I installed the snapshot. However when I try to set the "on above" or "startup max" settings, it does not save them. It looks like it doesnt seem to detect a change in these settings. Did I miss to update something? I did "flash new firmware image" with the link you provided. Thx

Thanks Tom, you mean these? Large BGE B: 0 P: 3 I: 0.008 D: 5 min fan: 10% max fan: 100% both fan and servo on Actually I just realised/found out that the PID parameters are different if you run in celsius mode (which I do). That might explain the "bad" results I had in the past with the...

Yes I'm using the offset rotary damper designed by Tom Kole. Actually I made two, one for my primo and one for the bge mini with a smaller outlet. If the pid output is at zero, the air flow is almost completely shut. In my test I indeed found the fire to be out when I opened the bbq...

Thanks makes sense. I was just trying to tune the PID parameters however using the manual tuning technique: https://github.com/CapnBry/HeaterMeter/wiki/PID-Tuning Guess I will need to make P even smaller than 1, starting at 0.1 perhaps?

Could you share your settings for the wga? Tried this weekend with the mini but didn't really succeed. I put the max fan on 25%, P=1, I=0, D=0 The bge went to 150C initially with setpoint at 105C and didn't manage to drop temperature for the next 3 hours (fan speed 0). Perhaps I should...

Hi. Finally got some time for a new session. I used these settings: 0/3/0.008/6 And this is the graph I got: The first lid open detection was a false one, so I increased the threshold from 8% to 10%. It looks like the pid is constantly overshooting and undershooting, and should stop a bit...

Has anyone tried to used the heatermeter + servo with a bge mini? Can it hold the temperature quite stable? Is a smaller fan required?

Hi Tom. I'm using these settings which I found for a primo XL: Bias: 4 , P: 1.5 , I: 0.01 , D: 5 They might not be suitable in combination with the servo perhaps? I won't have time to cook this week, but will post a graph next week.
