GCLOG is a lightweight daemon running in the background and constantly reporting your Geiger counter readings to various radiation monitoring websites. With a small footprint and minimal dependencies it is aimed to run on Linux embedded computers.

I've been using a GQ GMC 320+ V4 to upload data for about 2 months, the map shows:
CPM:25 ACPM:0 0uSv/h
Strangely it does update the CPM just fine. Not the ACPM and not uSv/h.
Is this related to the https redirects?
I have connected a GQ GMC 320+ v5 on a RasPi 2 Model B v1.1 running Raspbian.
The device is detected on /dev/ttyUSB0 and listed in lsusb.
The file gclog.conf is correctly configured to use /dev/ttyUSB0. When I start GCLog v0.2.4 (installed from the deb package), I get the following error every 2 seconds in journalctl :
Apr 17 10:06:59 pihole gclog[754]: [ERROR] Reading ZERO value from Geiger tube.
Any idea about the issue? Is there a way to troubleshoot the serial connection? The GC is working fine, and sending data to the GQ Windows software when connected to my PC.
I did a make from the latest on here, created a systemd service gclog.service, containing:
[Unit]
Description=GClog radioactive data feeder
After=network.target
[Service]
ExecStart=/usr/local/bin/gclog -v -c /etc/gclog.conf
Restart=on-failure
RestartSec=20s
[Install]
WantedBy=default.target
Then this happens at boot:

and the process just ends there. First it's strange it seems to run twice in a row after starting it from the service file, then it exits and deactivates, while nothing in the service would implicate this. SElinux or apparmor aren't running on this machine, so those can't be it.
Furthermore, when I run it by hand from the commandline, just running
/usr/local/bin/gclog -v -c /etc/gclog.conf
it does just fine and keeps running in the background, Entering main loop without ending....
What am I doing wrong here?
The upload to gmcmap.com does not work anymore.
journalctl shows
Apr 21 09:34:35 pihole gclog[30652]: CPM: 28 (= 1662/60), Timestamp: Sun Apr 21 07:33:35 2019

When I try to simulate an upload from command-line, I get:

So it looks like they're now redirecting all requests to https, which is not supported by the code in gclog.c .
After some time running gclog, the reported data is wrong:

When that happens, the only solution is to stop/kill gclog and restart it. No idea about what triggers this.
