@Per: The rain sensor should now show in the graph again.

fejan@home.se is not a registered user on Tellmon, but per.soderman@gmail.com is....

Telldus support wants to know if you guys (with non-updating sensors) are using Tellstick.Net or TelldusCenter.
Also Per Söderman: What is your login at Tellmon? I tried the email you use on userecho, but that's not the one.

Srdjan: Did you logout and backin to Tellmon? Seems push is still off on your user.

I've been running exensive logging and I do not receive any values for your sensors. Seems like Telldus simply is not pushing values for several sensors anymore. I'll raise a ticket with Telldus support.

The "last update" is gotten from Telldus. So they are receiving your data fine. It's just tellmon that does not get it.

I've had a look at your logged data. And I have not received any push data for those sensors since 26/2. But I can see from Telldus that they still are active. I've reset your push status .Can you login again now and check your sensors. That will cause Tellmon to ask telldus to start pushing your data again. Hopefully new data should arrive then.

I turn off monitoring if you have not been logged in for 90 days. Could that be the case for you? Seems it's logging now. Several of your sensors have values logged today.

This usually means that no data has been logged in the time range searched. 

The firewall does protocol inspection. So traffic on port 80 that does not adhere to the HTTP protocol is blocked. The blocking lasts 5 minutes only. So yes, it's time limited.

According to the logs you got blocked for doing a unknown HTTP command. I.e. something else than GET, POST, PUT, DELETE, OPTION, HEAD. The log does not state what. Are you running some funny software on your computer?
