It’s OK, but would be more accurate if you placed it at Østerås: https://goo.gl/maps/eZfmC2oXp2N2

Hey, that’s my unit!

Haven’t been logged in here in a while.

* No, it’s not mounted outdoors. Never have been. In May it was most likely in an office in Oslo city.
* Now it has moved to a basement in Østerås. I know moving it kind of ruins historical data, but the office was shut down. Please update it on the map.
* The link to show the increase is dead.
* I reported weird readings on this unit earlier in https://www.uradmonitor.com/topic/high-readings-after-firmware-upgrade/ so I don’t know if it can be trusted.

From yesterday evening it has been back in my apartment, running on yet another PSU. Slightly lower reading, but still way above the official readings for Oslo.

Ok. Trying another PSU now, just to check.

Hi

Update with new programmer (same one as in blog) went without a hitch. My node is up and reporting again.

Greetings, people. The unit is working now. But radhoo will have to update the location to Asker, Norway.

It seems the network was to blame. Not sure why yet, but I can experiment more after christmas.

I see http 1.1 is used. The main difference from 1 to 1.1 is that the connection is kept open, right? Perhaps that’s why it’s being mangled? I do have 4g internet at home, but not at work, so there must be something else messing it up there. Will bring it to a 3rd connection today.

I’ve got a new modem/router now (unrelated), so I’ll see over the weekend if that helps.

How ever, is there anything missing in the packets you see in https://www.uradmonitor.com/wordpress/wp-content/uploads/2014/12/Screen-Shot-2014-12-12-at-16.31.25-copy.jpg ? The requests look normal to me.

Yes, perhaps corrupted packets:

1199 5505.750204 23.239.13.18 10.42.0.22 TCP 58 [TCP Previous segment lost] http > metaconsole [SYN, ACK] Seq=142071037 Ack=1 Win=29200 Len=0 MSS=1460

Buy why? Bad soldering? Bad cable? Too low input voltage?

I have tried two different TP cables.

Connected via laptop to check out the traffic. Wireshark says the urad is getting “400 Bad Request”.

Perhaps this info can be found in OpenStreetMap. If not, that may be a better place to add it.

I know other projects use only specific data from OSM for their purpose, like this company http://www.openstreetmap.org/way/113512357 has a tag: payment:bitcoin=yes, and then some project show a map of everyone accepting bitcoin payment on their site.

MediaWiki is good. But I wouldn’t run all of this on the same server. Both the forum and wiki has a high chance of containing bugs allowing the server to be compromized. I can check if the hosting company I’m working for is willing to donate a small VPS for such things. That is, if radhoo is ok with not sitting on all the keys alone. =)

@Jeff: Yes, I vote for that one!

That should also give access to correcting which location the unit is at.

Good news!

Do you have room for more features in there? An avahi server whould be nice. Giving people with Mac or Linux (don’t know about windows support) the possibility of reaching it by typing http://uradmonitor.local or similar. No need to look up IP in router DHCP table.

How is the update performed? Via ethernet, or do we have to pop it open?
