Telldus has a public API (documented at http://api.telldus.com). One method in the API I can call is to turn on push messages for a user once he or she has logged on (this is done on Tellmon as soon as you login).

If you are a developer and want to get push for your own application you'll need to go though some steps:

1. Register as a developer at developer.telldus.com
2. Get your developer API-keys and develop your application. 
3. Register your application to get public API-keys
4. You'll need to setup a push endpoint (URL) and give that to Telldus

Once all that is done you can call the api-function setPush(true) to start having Telldus send sensor and device info to your application.

The data is actually just a normal HTTP POST message with some OAUTH headers for authentication and the device/sensor ID, timestamp and state/value.

For Tellmon the endpoint used is http://push.tellmon.net/ which you can actually visit in your browser. You can see that Tellmon is actually receiving about 150 values per second which is quite a lot.

You got the graphs working? Tellmon does not query Telldus live for data, instead it stores the data locally as its pushed from Telldus to Tellmon in real-time as your sensors and devices change state. 

Thank you for your feedback.

Tellmon gets the sensor/device list from Telldus via their API. You can logon to live.telldus.com and "hide" old sensors and devices there. Should reflect on Tellmon as well.

I'll take a look at the rain data stuff when I have the time. 

Try now. I had to move host from Azure to something cheaper. I've now merged the data logged from the old host with the new server.

The original min, max, average and sum statistics are now back.

Hi Mathias

It is Telldus that supplies the login service. Your user account is at live.telldus.com and it is this service that authenticates you and tells Tellmon that you have logged in. So any changes on the login mechanism must be done by Telldus.

All traces of your account, including alarms are now deleted.

Thank you for your kind words. I have been thinking about charging for some of the more advanced features. I only hesitate because I guess people will be even more demanding when they actually pay for something. I work full time as well as have a wife and three kids. There is simply not much time left to spend on hobby-projects like Tellmon.

To be honest I don't know. I'm considering shutting down Tellmon completely. It costs me about NOK 600 a month in hosting of my own money and all I get is users complaining about a free service not being up to their expectations. I do not own all the different kinds of sensors the users have. Thus it is very difficult for me to support tings like rain sensors, energy meters, blind motors etc. My attempt at adding support for the FooGadget Energy Meter in order to please some users, in turn removed support for rain sensors.

The whole project which started out as a fun hobby project has become an expensive and tiresome ting that requires a lot of support that I do not have the time to supply.
