I’m happy to report that there is a watchdog already:

If the unit is unable to connect to the server within 5 minutes, it will self-reboot.

You can try again, just wait 5 minutes.

Hi Daniel,

I’ve just compiled the code for your 12000021, and will be sending it over email.

This new firmware comes with the following improvements:
– dhcp fix
– lan access via port 80 (just open the unit’s LAN IP in your browser)
– json data for lan access
– some other minor fixes

I plan to write a quick article on the blog as a how to guide on how to update your firmware. Will be getting back here with the link when done.

Indeed the crystal needs to be replaced, as a quick fix to get the unit back online.

Thanks, they are in plan, keep the good ideas coming. We’ll also need stats of various types.

The 12000029 is experiencing a ” time dilatation” problem. As weird as it seems, this is what is happening: the quartz crystal responsible for accurate time measurement has failed (acting like a 4MHz instead of 8MHz), and needs to be replaced. Because of this what the unit should see as one minute is actually 2.04minutes. The DS18B20 that requires precise time intervals for initialisation is unable to measure temperature and shows -0.06. The CPM is double, as radiation is measured across a 2.04minutes interval. The duty cycle is half of what it should be.

Hopefully the unit will be fixed soon and get back online. For the moment I turned it off from the server side.

This was one of the strangest bugs to track as the quartz crystals only rarely fail like this.

Good initiative. Let’s see what can be improved.

Here’s how they are doing it in Finland: http://www.stuk.fi/sateily-ymparistossa/sateilytilanne/en_GB/sateilytilanne/
