Station’s Data Update Schema

There was an outage that was due to a MicroSD card failure of one of the Weewx servers collecting and sending weather observation data to station’s web server. Actually, there has been three Raspberry Pi computers involved in the process, two running Weewx and one Home Assistant.

While fixing this, Station Master decided to simplify data collection and update method. Previously data was sent separately from Davis, Weatherflow and Growatt equipment to web server. Now, all data is collected to Home Assistant using HA’s integrations, and then sent to web server in JSON format in a single call.

Data update frequency is now one minute, instead of five minutes before this change.

Home Assistant’s configuration is automatically backed up and backups are stored in cloud service. If there should happen a hardware failure, restoring the system is quite easy.
