Can you take a screen shot of the error and attach it to this post?
I don't have an Android tablet to test with. But I've tested with Safari and Chrome on iPad as well as Chrome and Firefox on an Android Phone (Android 4.4.3). Works fine on all.
Can you try the Chrome browser on your tablet to see if that works better?

The "last update" timestamp comes from Telldus and says when your Tellstick last received a value from the sensor. A sensor will happily resend the same value every X minutes (X depends on model) even if the value has not changed.
In order to save database space Tellmon only logs new values when the actual value has changed. As you can see from this picture:

Tellmon has not logged any data for that given sensor between 13:08 and 17:05. It could mean that the sensor did not send any values or as in in this case, that the value did not change and thus the last reading is still valid. The graph component is supposed to draw the line to the end in those cases. So there is a bug in the graph somewhere.
I'll look into it.

Tellmon does not currently automatically update the graph. You'll need to click the sensor to make it reload data. I'm working on having it auto-update when new data arrives.

I've tested with various PC browsers, an iPad mini and an Android phone. Those all look fine.

The bug is fixed and the range buttons as well as the channel selection now works as it should.

I can confirm something is broken on smart phones and tablet. I'll look into it.
Now that I have a scalable database export should come quite soon.

http v1.1 was released back in 1999 and all browsers and modern operating systems are using this now (including Firefox on Android 4.1.1). The few posts I've seen with people having this issue it was because they access internet via a Proxy (Squid etc) or had some firewall software that changed the HTTP 1.1 header to HTTP 1.0.
How is your tabled accessing the internet?
