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.
That's interesting. Most smart meters (at least over here) are have an impulse rate of 1000, so not an issue. In Z2M I believe this can be set.
Also I'm not sure what kind of "watts meter" you are using but the pulses from your meter determine how you are billed, which is what matters in the end. It also seems strange that the frient would so significantly under state the power you using when it's a relatively simple calculation unless the sensor isn't correctly attached and missing pulses. It's easy enough to check as your mains meter will also display the energy used on its LCD screen so you can compare this with any other measurement.
I note that mike.maxwell has mentioned in this thread that "they didn't send one of these" - which I take to mean there won't be a driver developed for the energy meter.
I had contacted Frient support team few months back and reminded them to send one device to hubitat team and they given the following reply. They may send it later once it’s back in stock.
“Unfortunately, currently, we cannot ship any of the Energy Meter Interfaces, because we do not have them in stock.
@Pradeep can you share what is your working Preferences settings with the Frient Energy monitor?
The 'Hourly Energy' should be working, or at least was working before.
