Meter configuration

• Communication - Select the type of communication you need to get data from your meter
  • Passive (Push) - Compatible with meters that sends data on a interval. This is the most common
  • Pulse - For meters that have a pulse output. Not very common, mostly used to meter sub-circuits of a larger installation
• Serial configuration - Configuration to communicate with meter. Please see Known hardware configurations
• Buffer size - Defines the buffer used to receive data. The size of this is highly dependent on the size of the payload the meter sends. For P1 meters you will sometime need 512 here to make it work properly. On ESP8266 the buffer size is very limited and is recommended to keep as low as possible, 64 is preferable.
• Voltage - You most likely have a 400V system even though you have 230V in your sockets. Your meter should be marked with either 230V or 230V/400V (which means 400V). Together with main fuse size, this is used to calculate the max limit for the graph.
• Main fuse - Size of your main fuse. Together with distribution system, this is used to calculate the max limit for the graph.
• Production - If you have solar power or other plant at home, add your peak kW capacity for the production graph.
• Meter is encrypted - Tick this if your meter has encryption and requires you to enter a Encryption key and Authentication key
• Multipliers - If any of the values presented in user interface or via MQTT is off by a factor, change this setting to correct the values

UART or GPIO pin for M-Bus is configured in the GPIO section if you have a development board
