Rock solid, prefer a reliable brand (who wouldn't...)
Report power down to a fraction of a watt so I can measure usage of low power devices. For example, if a device uses 1.2 watt, that's the number I want to see, without rounding it up or down to the nearest whole number.
IRIS plugs had that feature....but they are not easy to find anymore. However, I am not sure they did real time reporting, or the average usage over some period. Might be the latter, because it would take them some time after you plugged them in to start showing the usage. I only need the average usage, I actually don't need true real-time reporting.
Might be hard to find as reporting at the .1W level would likely create incessant updates flooding the Zigbee network. You could have a periodic reading but this seems better suited to a high speed serial or Ethernet product.
Even at a .1W change, does not mean you will have more reporting. If the device plugged in to it is a lamp, then if it's using 60W it won't vary in time until there is a change in state. A hot plate might have more reporting because it is turning the elements on and off to keep the temperature constant. When you see it reporting too much, just change the settings so tame it down a bit.
Ah, that makes sense. Because I checked my settings and also did not see fractions. 1 is the minimal configurable interval in the standard driver.
So that means I can't get this done regardless of the plug I choose, except the IRIS with the custom driver. Kind of puts me in a tough spot, because I'm trying to avoid using any custom code in my HE setup.
Yes good point, you mentioned that before. But ouch, at $50 a pop they are expensive....what else is good about them? Are they rock solid stable? My insistence on Zigbee is because these are critical devices for me, I have less trust in Zwave in general...
