Not a problem. I thought I had read it (about formatting the SD card) somewhere but have been reading so much lately couldn’t remember where or if it was even this project. When I realized I needed it for logging I went to the opensprinkler site, that seemed logical.
In any case THANK YOU to all that have made this possible, the idea, the kit, the firmware, the app. It all works as advertised, no problems assembling it or getting it to work. It is very intuitive to program, GREAT JOB!!!!!
