			* The meter is wired to the charger's '''Meter port''', not the DLM port.
			* The A and B wires are connected correctly. If the meter doesn't communicate, try swapping them.
			* The meter's RS-485 parameters (address, baud rate, parity, stop bits) match the values set on the charger.
			* The meter type (1-phase or 3-phase) in the Installer menu matches the connected meter.
			* The charger firmware and the app are updated to the latest version.
			* The meter is on the supported meters list. Chint meters must be OEM versions.
			* If you use CT clamps, they are calibrated and pointing towards the source (away from the charger).

			== Homewizard P1 dongle ==
			The P1 Dongle by Homewizard allows connecting directly to the electric company/distribution system operator (DSO) smart meter (where the operator supports such a possibility – check in compatibility section). This allows for a very fast installation time, as well as no need to do additional work in the house electric distribution panel. By connecting the EV charger and the P1 dongle to the same Wi-Fi network it ensures ease of use and everyday simplicity. Another benefit is you can use the same meter for general information on your electric consumption habits.
