Dials not updating

I run my own monitoring software but have decided to take a look at emoncms to see how that would fit in with my needs. I'm having a few issues, most of which seem to be due to the fact that I use Google Chrome, emoncms doesn't seem to like it (not able to edit things etc). 

 

Anyway, I'm pulling in some data from my UPS to test out emoncms, I can see the realtime graph updating but the dial widgets do not update. Using Chrome's inspector I can see that it is retrieving list.json for the dials and also data.json for the graph. The list.json contains data such as:

[["22","UPSRun",null,1351344661000,"540.85",2768,"1","0"],
 ["21","UPSRuntime",null,1351344661000,"32464",2840,"1","0"],
 ["7","UPSPower",null,1351344661000,"316",5563,"1","0"],
 ["6","UPSLoad",null,1351344661000,"15.8",5563,"1","0"],
 ["5","UPSCharge",null,1351344661000,"100",5572,"1","0"]]

I'm not sure what the 3rd parameter is, it always seems to be null.

The dials don;t work in Safari, or Chrome.

 

Any ideas?

 

Thanks
