Hi Charles,
I came across your PCB designs here https://github.com/hallard/WeMos-RFLink
which appear to be for RFlink running directly on WeMos ESP8266 boards, but I cannot find the WeMos-RFlink project mentioned anywhere on your site or blog.
If there is one, could you please post a link to any web page on it, or even a link to where the firmware may be found?
Thanks a lot,
