I have just implemented this on my Cinema template for the JVC projector and Oppo96 drivers. I have a small Enumerated Image widget with Red, Orange and Green square images for Standby, Cool-down(Starting) and Power-on. This is linked to the Power field, but would eventually be linked to a PowerState field.

The first thing I have found is that there is an issue with the JVC Driver. These are the states.

1. No Power to the projector so the Device driver is not on line. No image is displayed. OK

2. Power is On and the Red light is illuminated showing the PowerSate is in Standby. OK

3. Send a write command Power-on. The Power field turns to Green showing Power-on for 1-2 sec, but then goes back to Red as standby. If remains Red for some 15-20 seconds while the projector is booting up, then it goes to a permanent Green showing that the projector is ON.

4. Send a write command Standby to turn the projector off. The light goes Red for 1-2 sec showing standby, then goes Orange for cooling 10-15 sec before finally turning Red as it reaches standby.

I think this reinforces the point the that the write command for Power should be separated from the read command to access the state of the device. I see that you have specified this in the Projector section. I think it should be universally applied to all devices. Since adding these indicators, I have found the same problem with the Oppo93 driver where the single bol Power field switches backwards and forwards as the device boots.

Is this the best place to discuss this? If not , maybe you could move this to the device driver section to start people thinking about the issues with Power fields.
