New feature is graphs on the device page as well. You can see when a device has been on and off. Note: When using a remote to change device state Tellstick might not recognize the code. It depends on if you programmed Tellstick to use the same code as the remote, or another code to control a device.

If you control your device though live.telldus.com or tellmon.net you'll see the changes:

Nice feature!

What is the unit on the Y Axis? I see that my dimmers report different values (40-120?) while my on/off switches alternates between 0 and 250. Can it be used to quantify power usage?

Otherwise looks nice!

Best regards
Lars

Since dimmers report values from 0 for full off to 255 for full on I decided to use the same values for simple on/off switches as well. 0 means off and 255 means on.
To have the all on the same scale means that you can show them in the same graph if I choose to implement that later on.

Power usage is not something that can be measured though the Telldus devices. It would be cool though.

New release yesterday afternoon:
Fixed issue with location dropdown. Now you should be able to change location if you have more than one registered.

Nice! I miss the ability to overlay several sensor graphs though.

a nice feature could be if the graph would refresh itself and being able to pull it off the site to a desktop or android widget

Hello

Good work !

Hi

Could you add a function to include Wireless energy meter to http://foogadgets.tictail.com/product/w ... ergy-meter ?
This product convert blink to temperature ; ie : receive to 344.5°C corresponds 3445 blinks x 0.001 KW/h = 3.45 KW/h display on tellmon.net.

Regards

This device reports as a two temperature/humidity devices. I'm not sure how I can distinguish this device from normal temperature/humidity devices. Also the device will need some calculation on the server to display correctly.

Finally I'm not sure how many of these homebrew devices are out there. I'm not going to do a lot of work in order to support something only one or two people have.

I'd love to have the ability to register power usage myself. Unfortunatly like most norwegians I have an old "spinning disc" type of energy meter that is harder to read.



It has no LED, only a spinning disk with a red line that you might be able to detect if you have both a transmitter and a receiver LED and align the stuff just right. Might be easier to use a web-cam and OCR. But then no 433 MHz support.

@paaland there are 1-wire energy meters that can handle old spinning disks or some commercial ones but those will be harder to integrate with other DIY stuff.
They measure the change in reflectivity on the disk when the colored mark passes the sensor. (You could probably even build something similar with a lego NXT color sensor)

@paaland:
Its possible with this: http://www.smarthus.info/product_info.p ... ts_id=2925
Or clamp: http://www.smarthus.info/product_info.p ... ts_id=2824
Communication is Z-wave.. But solution exists
Or you can make a DIY with camera and OCR

As you say, there could be many different ways of doing this, so making a generic function is hard.
Im using Raspberrypi with lightsensor to count the LED-blinks and push them into DB and then calculate after.
There is also the Temp/Humi solution and the commercial ones probly have there own way also.

@paaland: could you contact me through my foogadgets mail found at http://foogadgets.tictail.com

It's should be king to include wireless energy meter on tellmon.net .
I think a low cost and predominately a very simple new product to measurement of the energy is born

regards

I'll release a new version soon. It will support the wireless electricity meter from FooGadgets.
Also I've created a community feedback site for feedback and support here: http://tellmon.userecho.com/
Use it to suggest new features and vote suggestions up or down.

I'll concentrate on developing the features more people want first.
