A smart meter is not a good way to measure power. First, a "smart meter" is primarily designed for energy measurement. Second, the limited capability to determine the load power on a smart meter is via some flashing spots (dots) and a stop watch. Not very good resolution for power.
A low cost instrument to measure power is a Kill-A-Watt and it works well even on very poor power factor. Its basic limitations in a US product are a nominal 120 V input and a maximum of 15 A current. In the far east there may be units for your voltages.
I believe the reason the Kill-A-Watt works well on low power factor is that a resistive shunt is used for current measurement. For example, a good quality capacitor load read 4.21 A, 3 W, 520 VA, and 0 PF at 123.1 V.
A moderate cost power and energy instrument is the TED system. But it still might have problems with your voltage source, and it has noticeable power factor problems. It can handle 200 A and resolve about 2 W.
There are many instruments available that are designed to measure power and will work with different input ranges. These probably start above $500.
Some newer scopes have power measurement capability. Otherwise you can do a volt * ampere * power factor measurement. Use an older scope to get an approximation of phase shift.
Clarify your goal.
You used the word consumption. This can imply energy. But if you have a smart meter on your home, or building and there are other loads also using power (energy), then it is hard to single out the consumption of only the fan. Thus, the reason to measure power of the fan alone. Then multiply power by on time of the fan to get energy measurement.
