Sorry about the delay. I am planning to work on 2.1.8 soon and currently the high priority is to address some of the issues in the firmware for OS 3.0 (such as losing support of static IP, which are not issues for OS 2.3 and earlier versions). There are also bug fixes such as the handling of remote stations when ‘special station auto-refresh’ option is off. In the long term, we do have an extensive todo list (for both OS 3.0 and OS 2.3), which includes features like pause station runs, integration of ET-based weather algorithm, improvements to push notifications and logging, integration with other sensors (including pbecchi’s sensor server) etc. etc. Of course not all can make it to firmware 2.1.8 but we will try to get as much done as possible in a reasonable amount of time.
