Q1: How can I determine if my meter is compatible?
A1: There are two ways to determine:
Method 1: Check if the meter has a "P1/RJ12" interface.
Q2: What are the requirements of the meter for P1 Meter Reader (P1-2W)?
A2: The protocol of meter will affect the power supply method of P1 Meter Reader:
DSMR5.0 meter: powered directly through the meter, no external power source required.
Other types of meters require an external 5V 1A Type-C power supply.
Q3: When connecting, is it necessary to "plug in the meter first and then turn on the power"?
A3: This order applies only to devices that require an external power supply.
DSMR5.0 meter: Since the P1 port has its own power supply, no necessity to follow the order.
Other types of meters require to always follow the rule of "plug in the power meter into port P1 first, then turn on the power supply" to prevent damage to the equipment.
Q4: What are the specifications for the external power supply?
A4: It is recommended to use a 5V 1A standard power adapter (P1 Meter Reader power consumption is about 1.1–1.2W). Do not use 9V/12V fast charging adapter,
otherwise it may damage the device.
Q5: Where is the P1 interface on the meter?
A5: The position, labeled either "P1" or "RJ12" by the meter manufacturer, varies depending on the meter model.
