    You should be able to use the most recent firmware, however, you would have to make sure not to set the blower in Voltage Mode, you need to use Pulse Mode because the HMv4.0 does not have the feedback circuit for the blower.

    I just looked at the online repository and find it odd that the last release version was in Feb 2016, but that is what I am seeing. I would suggest you use the latest snapshot release, which is dated April 2019, I always run snapshots on my HM and find them to be very stable.

    The HM update process has changed a bit since the 4.0 days, heatermeter.com/dl may be more up to date than what you are seeing in the online repository through your HM. If your HM software hasn't been updated in a long time you might want to go to heatermeter.com/dl and download the most recent release (I suggest latest snapshot) to update your system, make sure to select the proper rPi board before you download. (BTW latest release version on the above link is Oct 2017, I would still use the latest Snapshot release) You can either DOWNLOAD an image to write your sd card (via PC Win32DiskImager etc), select your rPi model and preferred wifi settings before you download... or you can click on the download.gz icon to download an image that you can flash via HM @ Config/System/"Backup / Flash Firmware".

    BTW if you are interesting in tinkering with your HM here is a link to a thread I made which details how to update your HMv4.0 hardware to the current hardware build.

    https://tvwbb.com/showthread.php?505...0+to+HMv4.1%3F

    It involves installing the RC filters on the probes and upgrading the blower circuit to the current hardware version. The RC filters are cheap and easy to install, probe stability will be improved with this update, highly recommended... The blower update is more difficult, benefit is you can use Voltage Mode for the blower, which creates less noise on the probes. If you do the blower circuit update make sure you follow the thread far enough to get the HMv4.2 update, the thread details updating from v4.0 to 4.1, and later to v4.2....

    I created the Roto Damper, RD3, HMv4.2 sliding back case, "air-burner" and the "ping-pong" valve in my quest for delicious "set and forget" BBQ.

    Hi Bryan,

    I was wondering if you noticed a bug in your heatmeter firmware. When configuring alarms, specially an SMS text alert for probe 1 low and high temp alert this is causing the pit setpoint to change.

    When I set the value to 150F hit save and apply, then enter 165 for high value and hit save and apply. This caused the pit temp setpoint to change to 165F. I was doing a live cook with a setpoint of 225F for my brisket and then I noticed that the setpoint changed to 150 and then to 165. I was looking at output saying 0%, but I wasn't at target temp of 225F. But then I noticed that the setpoint had changed to 165F.

    See image:

    I'm running the latest development build with a date of: May 20 2019 14:47:19 PDT

    I can't reproduce this at all. The SetPoint change only can happen if the alarm fires, which includes pressing the TEST button on the far right. If the setpoint is changing, that means that the alarm is firing to make it change.

    If you're sure that you didn't use the TEST button when saving, then maybe post a screenshot of your alarms settings (just the grid at the top) and I'll set mine up identical to yours and give it another try.

    I just updated the HM firmware from https://heatermeter.com/dl/. I loaded the file using the web browser and pointed to the v14 release. The previous version was from the 2016 timeframe (v11 I think). After the update, the extra packages that I installed from the System>Software menu were no longer installed. (I had installed Python-mini and "bc"). I have tried to load the available packages list, but nothing shows up in the tabbed A-Z index like it previously did. There are bunch of urls in the configuration menu where it gets the feed and the status says it downloads the list, but nothing shows up. I do know the "linkmeter" url was throwing an error.

    Not knowing exactly what I am doing I did play around to load it manually using "opkg update", the list was shown as downloaded. Then when executing "opkg find python" to test the list update, a response of "Segmentation Fault" was shown in the terminal window command. I'm not sure if this is related.

    I tried again by reflashing the SD card with the "latest development release" using the win32 imaging tool, but now I think all of my network settings were overwritten and need to log back into it to determine what is going on.

    Is there something missing or any suggestions on how to get the available packages to work again?

    I don't think installed packages ever translate over from release to release, only the configuration is backed up and restored on upgrade. That goes doubly because the older HeaterMeter releases had no way to track filesystem changes and only backed up the /etc/config directory. The v14 and snapshot use the new overlay filesystem method so it has a better idea of what to copy over when upgrading, but I'm almost positive it still doesn't do installed packages. When you upgrade you'll have to reinstall them each time, someone can correct me if I am wrong.

    I also think you have to comment out the linkmeter package definition in the list of package sources. I can't comment it out in the build because then the LEDE build process turns off all the HeaterMeter packages and doesn't include them, but at the same time if you have it defined, the opkg update fails because there's no linkmeter source in the official LEDE repository. Just put a # in front of the line and give it a try.

    If you ever use the Win32DiskImager tool to flash the SD card, it wipes the filesystem completely. All network settings, configuration, installed packages, and any edited files are reset to default. If you download a pre-configured image, those are applied on top of the default config, so the same warning applies.

    I'll try again with the development version. I did comment out the linkmeter URL and rebooted several times, but no luck with loading a list of packages. Commenting it out does remove the error that I was initially seeing.

    Still no luck. This is a fresh image v14 release that it quite working on. The previous release ~v11 worked ok. I did restore a backup from v11 to v14 and then the packages were populated, but the linkmeter tab was empty saying it couldn't communicate with the AVR. So I reflashed it and the linkmeter is back, but no packages are available. It shows success on downloading the lists after pressing the Update lists button, but the A-Z list is empty/none.

    Code:
    General options: (nothing changed)
    dest root /
    dest ram /tmp
    lists_dir ext /var/opkg-lists
    option overlay_root /overlay
    option check_signature 1
    
    Distribution feeds (commented linkmeter, uncommented last two)
    src/gz reboot_core http://downloads.lede-project.org/sn...m2708/packages
    src/gz reboot_base http://downloads.lede-project.org/sn...jzf-s_vfp/base
    # src/gz reboot_linkmeter http://downloads.lede-project.org/sn..._vfp/linkmeter
    src/gz reboot_luci http://downloads.lede-project.org/sn...jzf-s_vfp/luci
    src/gz reboot_packages http://downloads.lede-project.org/sn...s_vfp/packages

    I just took a fresh clean snapshot install (Win32DiskImager written, but shouldn't make a difference), went to System -> Software and hit the "Load lists" button. Waited and it all completed successfully, then searched for python-light and it was there ready to install, same thing with bc. When I looked at the A-Z list there was nothing there at first, but after a few seconds it loaded (3 seconds thereabouts). I didn't edit anything apart from setting up the wifi.

    This was on a Pi Zero, which looks like what you've got (or an original Pi A or B), right?

    I am using the Pi A+.

    I tried the V14 image a few times again with no luck. I also swapped out for a fresh SD card with the same result. For some reason I cannot get the packages to show up like before. I am out of ideas after spending a couple hours trying different things and even trying to revert to an older image, but the HDMI doesn't want to work so i can configure the network settings. Frustrating in trying to recover a good configuration again.

    Code:
    Downloading http://downloads.lede-project.org/snapshots/targets/brcm2708/bcm2708/packages/Packages.gz
    Updated list of available packages in /var/opkg-lists/reboot_core
