    Trouble with Pit Probe 0

    Awesome, great troubleshooting Mike, and glad you got it working before I even was able to see this thread. Go go community!

    What is this?

    It is telling you there's excessive noise detected on that probe. Red would indicate a virtually unusable signal. If you're logged in and on a recent snapshot, you can click on it and it will display a graph dump of the last probe read cycle. Probe noise can come from moisture getting into the...

    Heatermeter with BGE Minimax

    The defaults are designed for a BGE Large, which is what I have and do all the testing on. The PIDs were developed for blower-only, but they work great with a damper as well. It is usually less about the PIDs and more about not letting too much air get in when the output is 0%.

    ATMega328P failure? Diagnostic advice please?

    I've never seen an ADC go bad before. Did you check the configuration in the webui to see if the probe configs just got scrambled somehow? You could also try doing a "Reset Config" from the LCD menu on the device itself to reset everything to default. This also wipes the Pi's config but if you...

    Library for Eagle 6.x?

    You can just copy paste them from the HeaterMeter schematic into your design or into your own library, but here's the whole library.

    WSM 22 and Heatermeter with rd3

    I don't think PitDroid has any configuration items in it. You just go to the webui with a browser and change them, use whatever the IP address you put into pitdroid except use a browser.

    WSM 22 and Heatermeter with rd3

    Yup, just set "Fan on above" to something higher than 0%, and "Servo fully open at" to something lower than 100%. You can overlap them but I have my BGE set to Servo fully open at 50% and Fan on above at 50% so the damper fully opens, then the fan turns on after that.

    Station keeping PWM servo pulse?

    Ah-ha! I thought that when I posted at first but didn't think to mention it because that code was so old and you had referenced the newer code so I assumed you were building your own firmware from HEAD. It was a big point of contention back then, where I thought the servo should always turn off...

    Station keeping PWM servo pulse?

    It was in manual mode 0% with a 4.3.3 HeaterMeter with the Pi hooked up and booted and running for about 5 minutes. I have no idea why you wouldn't be able to see it unless you're running an old version of the HeaterMeter code. What you're seeing used to be the way it worked a few years back?

    Station keeping PWM servo pulse?

    I just verified with my scope to be sure, constant 50Hz signal, as expected.

    Quarantine Rib Cook

    Eh I decided to just let the user decide if it is too much information at once. Snapshot 20200329 you can select "Show Fan/Servo" from the dropdown.

    It would be nice but the problem is that fan and servo are both filled graphs, so one will be on top of the other and it is very difficult to read. I tried stacking them at first but it gets impossibly confusing at that point because they don't actually add up so displaying them that way...

    HeaterMeter Hardware v4.3.3 and v4.3.4

    It is probably the same as all the other ceramic grills. Just get a piece of sheet metal from the hardware store that's big enough to cover the vertical height of the vent, cut a rectangle out of it, then cut a hole in the center and put a 1" NPT nipple in it and secure it with a nut (the EMT...

    Fusion 360 issues

    Yeah the nice thing about the HeaterMeter board layout is that it is secured on both sides of the case by the connectors. The Pi Zero is so light and the 26 pin connection holds it so well, that there's nothing that really needs to be done to hold the Pi.

    Station keeping PWM servo pulse?

    You should see a 50Hz signal coming out of PB0 at all times the HeaterMeter active is in Auto or Manual mode.

    Fusion 360 issues

    I think 2line-TC-RPi-A+ (or the probe version) might already fit a Pi Zero and not have any holes?

    HeaterMeter Hardware v4.3.3 and v4.3.4

    Heck yeah, we did it! Thanks for sticking with it and being such a great set of eyes on your board. Always makes me happy when we can solve a problem like this. The open and closed positions you just need to edit the "Servo pulse duration" values in the webui and you're good to go.

    Fusion 360 issues

    If you're talking about the 4.2 case, then I had no problem loading it in Fusion360 but I did it a long time ago. If you want to copy my imported version with a couple changes, I've shared it https://a360.co/33RgWzi

    Station keeping PWM servo pulse?

    I'm not entirely sure I am following your question, but SERVO_HOLD_SECS now only affects the servo signal when the controller is in OFF mode (long press left button, or set the setpoint to "OFF" or "O" in the webui). When the servo goes to OFF, it waits SERVO_HOLD_SECS as the servo travels to...

    HeaterMeter Hardware v4.3.3 and v4.3.4

    Well that's not exactly the stellar improvement I'd hoped for, but you know what? I just learned something. The RST is actually 2.78V. I just assumed that the 10K pullup was just a pullup, but it actually draws more current than I expected. I have 2.8V on my RST pin so that sounds good. I think...
