Hi,

FYI, I just posted updates to the software application (v1.0 build 28079), firmware (v41), Interface Wiring Maps, and User Manual. This is a summary of the changes:

1. Updated Hysteresis Device Elements to include an Active Low setting (for active low relay boards) and an offset model. The offset model permits the Target to be adjusted while keeping hysteresis window the same.

2. Added Yun Shield support. The Yun shield facilitates Wi-Fi or Ethernet configuration. Note we have noticed this shield may impart some timing delays (likely due to the onboard Linux OS), so we suggest it not be used time-specific / critical applications. Fermenter control, etc. is fine, but discuss your application with us before implementing.

3. Added ESP8266 integration (except RTD support). NodeMCU and Wemos D1 are supported, and most other ESP8266 configurations should work out of the box.

4. Updated local LCD control. One 20x4 LCD can be added for interface-local data presentation (per discussion above). This was previously implemented in the software but we made some enhancements for speed and usability.

NOTE: BruControl build 28079 and firmware v41 must be used together! To update, close BruControl. Update the interface firmware, then start the new version of BruControl. Note the Hysteresis device elements must be updated to set the proper On Offset (Hysteresis window).

As always, let us know if you need any help.
