Over the last couple of weeks Paul Burnell @pb66 and I have been working through the future direction of emonhub and how we can bring the different versions together. Its a big project, so we are not there yet as there is a lot of detail to work through and we’re taking the opportunity to really look at how emonhub should work from the ground up.
Last year Paul raised with me a number of issues with the emon-pi variant that I created, including:
- Threading bug where the MQTT and http interfacers where not running properly on their own threads - fixed July 2017
- http interfacer ever increasing queue if not configured properly potentially causing potential memory issues - fixed October 2017
- http interfacer implementation that attempts to send the entire buffer content in a single request to the remote emoncms, likely overloading the emoncms installation or/and failing resulting in a repeated attempts.
Having not quite understood how emonhub worked when I created the emon-pi variant I had somehow removed functionality that did work and replaced it with something that didnt work as well. I have now reverted the buffering code on the emon-pi variant to mirror @pb66’s experimental branch to fix the buffering issue.
The latest version of the emonhub emon-pi variant with these bug fixes is now available (release v2.1.0). This is in an interim update to the emon-pi variant as we are still working through our discussion of the future direction of emonhub as mentioned above.
