The Piri company provided us for testing remote controlled socket WiFi 2.4GHz which measure the power consumed by the connected device. In the video you will find the results of the socket tests, we will also look inside the housing.
Control of switching on the connected device and reading of power consumption is possible thanks to the smartphone application: Piri smart home .
The socket is compact and ready to use out of the box, it can switch power up to 3kW, while the application guides you through the process of connecting to your home WiFi network. We set up an account in the operator's cloud in the application using the e-mail address you have. Put the device into pairing mode by holding the button for 5 seconds, the diode will flash quickly. In order for the application to connect the socket to our WiFi network, the AP should broadcast the SSID of the network, and the MAC of the socket must be on the list of devices allowed to connect to our WiFi AP.

DEVICE CONTROL
The device connected to the socket can be controlled:
- a manual button on the socket housing,
-from any place in the world where we have access to the Internet, using an application on a smartphone,
-with the use of on and off schedules, as well as a timer configured by the application.
The schedules set in the application are run in the operator's cloud and the socket will be switched regardless of whether our smartphone and the application are connected to the Internet. The condition for remote control of the socket is its constant connection with the Internet.
OPERATION AND NEST CONSTRUCTION:
Link
The application is convenient to use, but minor adjustments would be needed, e.g. the cracking of messages in the operation log and increasing the resolution of measurement points on the timeline.

It is worth taking a look at the YT Piri channel, you will find there materials both about the WiFi socket and, for example, about a wireless camera:

The socket, when working with ~ 230.8VAC power supply, consumes 3.14mA with the relay off and 6.73mA with WiFi activity, and 9.44mA with the relay on and 11.64mA with WiFi activity.
Comparison of device indications with a connected light bulb is 158W in the application on the smartphone and 148W from the indications of connected multimeters.
Connecting the iron gave the indication 1092W in the application, the multimeter indications are 1013W.
Connecting a 1uF capacitor showed 0W, while the ammeter showed 73mA Bravo! the socket actually indicates active power .
Another PF (power factor) measurement could be useful.

We look inside the socket and the thoughtful compact design immediately catches the eye. Easily locate the measuring resistor and the WiFi module.

The WiFi module is based on the Mediatek MT5931 (802.11n 2.4HGz) and ARM MC101 system, after a while you can find information about the module on the network: Micro UART To WiFi Module . The WiFi antenna is made in the form of a section of wire - there is scope for development towards a PCB or ceramic antenna.

On the board you will find a 250V / 16A relay that controls the connected device, a switching power supply based on LNK306N, the HLW8012 power measurement system and the STM8 8S003FP6 microcontroller. You can find more about the power measurement system, e.g. here: HLW8012 .

Where do you see the application for a remotely controlled WiFi socket with power measurement?
Personally, I see an application in controlling electric heating and air conditioning (provided that the air conditioner starts when powered). The power measurement function can help to optimize energy costs, while remote control and scheduling can facilitate the ongoing control of the connected device. During an unexpected change in weather or a change of plans, an outlet could turn on heating or air conditioning and prepare the house for our return.
There are days when such an outlet could be useful to start the coffee machine in the kitchen, when the alarm clock in the bedroom keeps us awake
- of course, one should "arm" such a coffee machine the day before ...
An interesting development of the structure would be the possibility of indicating other parameters in the application, apart from active power / energy, e.g. power factor, mains voltage, current consumed by the receiver, counting inductive and capacitive reactive energy. Even if the values were approximate as in simple energy meters: measurement of active, reactive and apparent power that would be an interesting feature. Perhaps such functionality can be added by changing the firmware and by expanding the application?

We previously tested wireless outdoor WiFi camera also made available by Piri.
