Hi Juzzie,
This is my oversight, the code checks for username/password when starting up MQTT - reading your posts above you don't use username or password for MQTT. I need to fix this.
Leave this with me!
Update:
This should be fixed in the v0.4.1 release

One question - why ntp.org?

I looked up ntp.org before asking the question, so was aware of it's function' But I had previously assumed that the time was obtained from the local network (my server), or directly from my isp.
The idea behind ntp makes sense, though if the time were obtained from my local network it would grant a little more autonomy.
I wonder if the espgeiger regularly checks ntp for the time? I don't imagine the clock in an esp8266 is very good at keeping time over a long period.

From what I can tell the ESP8266 requires the use of the millis() function to maintain time, so it will drift over time, especially if the load becomes high on the ESP. I suspect it does re/set the time every so often. Paul will be able to confirm this. A couple of useful bits here:
https://forum.arduino.cc/t/setting-the-esp8266-internal-clock/680099
and

Juzzie, do you run your own local NTP server at home? Maybe there could be an option in the setup of the ESPGeiger to have a custom NTP server?
