I would like to start measuring my energy, water and gas usage. However I am not sure how to do it.
I've got this energy meter:
This is how my gas meter look like:
My watermeter
I could not find any solutions for recording a "draaischijfmeter [dutch]. My gasmeter appears to have no reflecting area in any of the numbers and I also could not find any real magnetic area on my watermeter. Does anybody have an idea how to measure any of the above meters?
kind regards
Joris

Joris,
This is not 1-Wire but you can use an RFXMeter with an RFXPwr module to measure the power usage,

And 2 RFXPulse modules with a Reflective Optical sensors to measure gas and water usage,

To receive the RFXMeter information you need a 433.92MHz receiver

And sofware to process the data:

Bert,
He says he doesn't have any reflective area on the meters.

The watermeter has a reflective zone at the wheel (0.0001), right above the number 66584314.

Yeah, you are right. I must be able to use the CNY70 for detecting a turn of the watermeter.
Are there people who used the CNY70 for the "draaischijfmeter" also? Detecting the black non-reflecting part of the disk?

BTW; you can use a clamp for power measuring [:D]...
