I saw another thread in our hubitat community where some initiative is happening to integrate the Frient devices.
So, we may be able to use Frient devices in the future.
In my case I took some work around to integrate this Electricity Meter Interface to Hubitat. Even though our community members tried to develop a device handler for this , it didn’t get succeeded due to the unavailability of simple power refresh method.
As suggested by the community member, I tried with Generic Zigbee Outlet driver and the meter interface started fetching the power consumption, but the value was very low.
In my case I was facing 2 challenges.
- Frient Meter interface is designed to read 1000 pulse /kWh(Default)
- My Electricity meter was providing 600 pulse/kWh (Don’t remember exactly but sure it’s not 1000 pulse)
I took few of the devices like a 7 watts LED bulb and 800 watts hair dryer and then measured the exact wattage of these devices using a physical watts meter. Later isolated the grid connection from home circuit and connected these LED bulb and hair dryer separately and measured the value providing by the Frient Meter Interface. In my case the power reading was 22.28 times less than the actual value.
I created a virtual energy monitor and few variables in hubitat and used the calculation(Virtual HEM = actual reading*22.28) to display the wattage. Later I checked the wattage using air conditioner, geyser, Laundry Dryer and even with a 1 watts LED indicator and it’s shown the power consumption as low as 1 watt to 4500 watts.
It’s not a 100% accurate or a proper solution but at least in my case it serves my purpose and I will get a notification in the event when my kids or somebody turns on AC/Geyser etc and when it’s running for a long time.
