The updated boards arrived and I have completed a test build. Apart from being fooled by a BMP-280 sensor which actually turned out to be a BME-280 sensor - it all went well. I am still waiting for the new NCH6300HV power supplies to be despatched so for now I have wired to an NCH6100HV which has the same connections but is a little bigger. There are some software changes I want to make but nothing major and I have commenced a write up for the project here: http://www.nixology.uk/sp-101/sp-101-wemos/ More pictures will be added soon! Boards for the SP-353 variant are on their way and I'll report on that as and when. - Richard
