v1.0.7

• Fix packet emission loop

  With the changes of the previous release, push (broadcast) packets prevailed to the point where no push packets were emitted anymore.

v1.0.6

General

• Add data packet watchdog (#11)

  If no data packet is emitted for a configurable count of iterations, an error will be raised, in turn crashing the engine (and potentially triggering a restart).
  The count of iterations can be configured by adding the max_no_data_iterations option in the driver's section (default is 5). An iteration will happen every 5 seconds when no data is received.

  Thanks to user cube1us debugging this issue.

HTTP

• Retry failed HTTP requests
  If HTTP requests fail, the driver will attempt to send them again up to 3 times. Should none of the attempts succeed, an exception will be raised.

• Make HTTP requests honor socket_timeout option in configuration (#11)

  Thanks to user cube1us debugging this issue.

Configuration

• Configure accumulators for custom observations defined by driver
  rainCount is accumulated by summation and for rainSize the last available value is used.
• Move example configuration from installer tool to configuration editor
  Example configuration now includes comments.
• Remove polling_interval from default stanza
  It isn't a required option as a sensible default is set.

Logging

• Change log message to not read like an error
  Mapping debug message previously read like an error message. This is now improved.
• Reduce chattiness of driver during normal operation (#10)
  The driver previously logged INFO messages when emitting packets. This was changed to DEBUG.
• Add additional log messages when receiving and decoding broadcast packets
  When receiving broadcast messages, the size of the packet will be logged and a message will be printed when creating packet objects.

v1.0.5

• Fix interrupts and signals being caught in main loop (#4)
  Interrupts and signals were caught in main loop, preventing WeeWX from being stopped using Ctrl + C or other signals used by the service manager.
• Fix log messages in the main packet loop not respecting log_success configuration option (#3)
• Completely rework scheduling logic
  All scheduling is now centralized. This should prevent any tasks to be executed immediately one after another. Push refreshing is now performed every 20 minutes and is scheduled using a integer factor of polling events

v1.0.4

• Fix high CPU usage (#2)
  Due to not blocking the loop when no packets were available, this driver caused WeeWX to have an absurdly high CPU utilization. This is now resolved by pausing the loop until a packet is received (or an error is caught). As a safety measure, the driver checks for new data every 5 seconds anyway.

v1.0.3

• Fix broadcast activation failing after some time
  After an irregular timespan (usually hours to days) broadcast activation would silently fail. This was due to the polling and broadcast activation happening at the same time. The WLL however is unable to cope with multiple simultaneous HTTP requests.
  This was resolved by implementing a centralized scheduler to avoid multiple tasks being executed simultaneously.

• Switch all driver threads to "daemon mode"

v1.0.2

• Fix incorrect rain diff calculation
  Previous amount needs to be subtracted from the current amount, not vice-versa.

v1.0.1

Fix incorrect rain mapping

Storing the actual floating-point value of the rain amount for calculation would cause the rain amount to be reported too low due to floating-point precision errors.

Instead, only the count of spoon trips (an integer) is stored.

Additional rain observations

Additionally, the rain mapping now exposes three more values:

• spoon trips since last record
• rain rate in spoon trips per hour
• size of spoon in inches

The first uses the unit group group_count, the second one group_rate (see below) and the latter group_rain.

New unit group group_rate

A new unit group group_rate is defined. Currently it contains only one unit per_hour.
group_rate is intended for observations measuring the instantaneous rate of some event. I.e. how often something it would happen in 60 minutes if the event continued to occur at the current rate. This is comparable to "rain rate" except that it is intended for concrete, countable events.

The driver only uses it for the rate of the rain collector spoon tripping.

Other bugfixes and changes

• Improve error handling in UDP broadcast receiver
• Improve closing of UDP broadcast receiver
• Make rain mapping and wind service None-safe
• Convert all caught errors in driver to InitializationError and WeeWxIOError. This improves integration with WeeWX's automatic retries.
• Minor refactoring
