    I tried to re-enable and went to login - it says only system admins can now access.

    Yeah. Itís gone. Mine stopped working today.



    Reluctant to throw it in the recycling, but doubt prodding it is going to reveal anything usable.

    Did anyone come up with an easy solution to this?

    I don't have any energy monitoring currently and would like to invest in one rather than go down the smart meter route.

    I have built a Gas Meter measurement device based on the ZWave Fibaro Universal sensor (old Style). It has been running successfully for over 2 years. It is fitted on a conventional revolving wheel type meter.

    The circuity is simple and uses the OPB732WZ Opto Switch connected on IN1. A suitable 1W (at least) current limiting resistor (value depends on voltage used) is used to power the LED.

    As the wheel relvolves and zero passes under the device, light from the led is reflected by the silver portion of the wheel onto the LDR connected to IN1. Vera can be configured to detect the change.

    Software is installed on Vera to detect changes in the state of IN1 and some simple calculations will determine how much gas is used.

    Installation is a little fiddly. To set it up, run the gas until zero is showing on the right hand wheel. You will need a voltmeter which needs to be connected between IN1 and ground. Place the opto device over the wheel and move it around, you need to find the place where the voltage is as low as you can get it, in my case that is around 0.3v. Then use bluetac to hold the device in place.
