Electricity meter with remote reading capability?

Question

Iron

I am looking for a 3-tariff electric meter with the possibility of remote and wireless reading. It is needed to play around - to see, for example, how much electricity the air conditioner ate during the night. Or how much electricity it takes to boil a kettle.
The electric meter will stand outside the apartment, but next to the front door. Bluetooth connection options should work.
What do you advise?

Answer 1

One of the most common options is suitable - mercury 201. An electronic meter with a CAN interface. You will need to stretch an additional wire and buy a CAN interface for the computer. An important point: for some models, the contacts are under a sealed cover.
But it may be easier to play around with current clamps. It will be much more convenient to look at the current consumed by a particular device.

Answer 2

Here is a list of supported counters that you can go over for an overview of what is on the market. To interrogate the meters, you can use the manufacturer's configurator programs, you can, horrified by the user interface, request a description of the data exchange protocol and sprinkle something of your own, or you can look for something complex, but free, for example, this .

Answer 3

Yes, by the way, household domestic counters with bluetooth and Wi-Fi do not exist. There are three main options for remote polling: wired (RS-485, RS-422, CAN), power network (PLC), radio (most often ZigBee). In the last two cases, you will need additional equipment (PLC hub, radio modem), and the meter itself will be more expensive. The optimal solution is a meter with RS-485; RS-232 or USB to RS-485 converter - from the Chinese (DX or any other store), preferably with galvanic isolation. If full-fledged monitoring is required, the meter should be with a power profile, without it only daily or monthly energy is available, but you can arrange a periodic poll of current readings and calculate consumption per interval from the difference between adjacent readings (less accurately).

Answer 4

if you for

how much electricity did the air conditioner consume per night. Or how much electricity it takes to boil a kettle.

then perhaps it’s better to take a rosette, in bulk, even a megaphone has something
