The package contains 3 pieces of PZIOT-E02 phase meters. The above price applies to 3 pcs.

The PZIOT-E02 is a compact, DIN rail-mountable consumption meter that can accurately measure the current of the household or inverter output up to 100A.

Recommended especially for,

- those who do not have a P1 port meter
- or who want to measure the production per phase directly at the inverter output.

This way, the PZIOT-E02 measurement can be compared with the feed-in measured at the P1 port, and the real household consumption can be easily calculated.

- WiFi hotspot installation – quick setup
- Automatic data sending to the smart electricity meter system
- MQTT integration – no extra broker configuration needed
- Reliable measurement up to 100A

Wiring
- PZIOT-E02 → according to the manufacturer's diagram.
- Power supply, then connect the PZEM meter head to the desired phase (L1/L2/L3). Lead the phase downwards from the top.
- It is advisable to install a separate circuit breaker for the power supply to be able to turn the device on/off.

First start / setup
- After powering on, the device creates its own Wi-Fi hotspot named ADA-PZEM.
- Connect to the AP, open the setup interface with the QR code or in the browser at http://192.168.4.1 (setup).
- Enter the Wi-Fi, (if needed) MQTT, email/device password.
- If there is an ADA P1 Meter device on the network, do not enable the MQTT connection!
- Save → device restarts, then connects to your own network (STA mode).
- Then the web interface is accessible via local IP.

Reset (clear settings)
- The device must be on.
- There is a recessed button on the front. Press it once briefly; this will erase the settings and restart the device in AP mode for setup.

Commissioning → Standalone phase measurement (for meters without P1 port):
1-phase system:
- Connect the PZEM sensor to the single phase (L1).
- On the PZIOT-E02 web interface, set the selected phase (Select: L1).
- You will see voltage, current, instantaneous power, and accumulated energy on the local UI/JSON.

3-phase system
- Choose one phase to measure (e.g., L1) and connect the PZEM to it.
- (If you want all three phases separately, you need 3pcs PZIOT-E02.)
- On the web interface (http://pziot-e02.local), set the phase Select according to the wiring (L1/L2/L3).
- Then the device continuously measures and provides the data for the given phase via the local interface/API.

Commissioning → with ADA P1 Meter (okosvillanyora.local:8989):
Wiring: the PZIOT must be connected to the inverter phases before any other load.
Local network: the ADA P1 Meter and the PZIOT-E02 must be on the same WiFi (otherwise they cannot communicate). 
Phase designation on the PZIOT: on the web interface in the Phase Select field, set which phase it measures (L1/L2/L3).
Data transmission: the PZIOT-E02 automatically sends the phase data to the ADA P1 (locally via HTTP at okosvillanyora.local:8989), so no separate subscription is needed.
Cloud: the ADA P1 incorporates these "plugins" data and forwards them to the okosvillanyora.hu cloud – thus, production/phase-level measurements also appear on the usual dashboard. The HMKE.APP automatically displays apartment consumption and inverter production.

The device can also be used with Tasmota firmware. Follow the instructions in the description for its installation.

Factory Reset (firmware erase)
- The device must be off
- There is a recessed button on the front. Hold it down and turn on the device. The system will then delete the firmware from the device, indicated by blinking red LED.
This action is irreversible, permanently deletes everything from the device, and only Tasmota firmware can be installed afterwards!
