Ecowitt driver for homeassistant

ecowitt:
  port: 4199
  barounit: metric
  windunit: imperial
  rainunit: imperial
  windchillunit: hybrid

Windchill can be one of "hybrid", "old", or "new". Defaults for units are as shown above. The only mandatory "option" is "port". Units can be one of "metric" or "imperial".

This device expects to be fed data from an ecowitt during hass startup. Without this data, it doesn't know what devices to wire up. Hopefully I can fix this in the future, but for now, do the setup on the ecowitt device first, then add this to your configuration.yaml file. If you do not, hass may hang on startup.

Use the WS View app (on your phone) for your Ecowitt device, and connect to it. Pick menu -> device list -> Pick your station. Hit next repeatedly to move to the last screen titled "Customized"

Pick the protocol Ecowitt, and put in the ip/hostname of your hass server. Path doesn't matter as long as it ends in /, leave the default, or change it to just /. Pick a port that is not in use on the server (netstat -lt). (4199 is probably a good default) Pick a reasonable value for updates, like 60 seconds. Save configuration. The Ecowitt should then start attempting to send data to your server.

Add config as shown above to configuration.yaml. Port is required. Pick the same port you did in the wsview app.

If you set a really long delay on updates, homeassistant could take awhile to start.

If you get an error in the logs about an unhandled sensor, open an issue and paste the log message so I can add the sensor.
