Ingenieurbüro Irradiance Sensors
The purpose of this plugin is to collect data from Ingenieurbüro Mencke & Tegtmeyer GmbH Irradiance Sensors.
The purpose of this plugin is to collect data from Ingenieurbüro Mencke & Tegtmeyer GmbH Si-RS485 Series Irradiance sensors (see: See: https://www.imt-solar.com/fileadmin/docs/en/products/Si-RS485-Selection.pdf), via Modbus serial or TCP. Please follow the documentation carefully when installing the sensors. The plugin reads serial data at 19200 BAUD, with NO parity, 8 bits and 1 stop bit. Data will be collected to the
weather table. By default, it will collect data every 5 minutes, but can collect at a much faster rate depending on the speed of the serial connection. The plugin will make 1 attempt (by default) to read the data. The following data will be collected. This plugin relies on the Modbus Ardexa plugin.Variable Name Units

Arguments are as follows:
endpoint. This is either a serial device like/dev/ttyS0or an IP or DNS like192.168.1.15bus_addresses. A Modbus address in the range 2-255. This can be a hyphenated list like3-10or a list like2,5,7,9--port. This is an optional parameter used in an Ethernet gateway, and is the TCP port used for the gateway. Default is502--attempts. This is an optional parameter, and determines how many times to times to attempt to read an inverter value. Default is1--delay. This is the delay in seconds between inverter send and receive commands, AND ifattempts> 1. Fractions like0.3can be used. Default is0.05--stop_on_any_command_fail. If this is specified, then any Modbus commands that fail will stop all further queries for all bus addresses and attempts.--serial_lock. If this is set, the program can only be run one at a time (so as not to overload a Modbus device). If the device being queried is a serial device, this will automatically be set to "on". For IP addresses it is optional.--sampling_rate. If this is defined, and the sampling rate is greater than 1, then allDECIMALandSWAP16values will be collected as an average. In other words; it will take a sample at the nominated frequency. After X samples defined bysampling_rate, a record will be written and sent to the cloud.
