Misol Weather Station Component

.. raw:: HTML

This is an implementation of the ESPHome component for a Misol weather station with RS485 output. The weather station is a combination of various sensors, including temperature, humidity, pressure (not available for all models), wind speed, wind direction, wind gust, accumulated precipitation, light, UV intensity, and UV index.

The weather station uses serial communication with a baud rate of 9600 bps, 8 data bits, no parity, and 1 stop bit over RS485. The weather station sends the data every 16 seconds. This interval is not configurable. The weather station only sends the data, and it does not accept any commands. To use this component you will need to connect the weather station using RS485 to the TTL converter.

There are 2 versions of the weather station available at the moment: with and without a barometric pressure sensor. The component will automatically detect the version of the weather station and will provide the data accordingly.

This component requires a UART Bus <https://esphome.io/components/uart#uart>_ to be setup.

Component/Hub

The component acts as a hub for the weather station sensors. It reads the data from the weather station and provides it to the sensors.

Example configuration:

.. code-block:: yaml

misol_weather:
  id: weather_station
  uart_id: uart_bus

Configuration variables:

• uart_id (Required, ID <https://esphome.io/guides/configuration-types.html#config-id>_): The ID of the UART bus to use for communication with the weather station.

Sensor

The sensor platform allows you to get the data from the weather station.
