Greetings Ray,
I am sorry if my comments were perceived as a criticism of your awesome work, and if so I unreservedly apologise. Your rapid response is a tribute to your excellent customer service and sets a benchmark that not many others can achieve. Thank you.
I have followed the installation instructions, verbatim. I cannot get the cron job to automatically start OpenSprinkler on reboot. I know that I will work things out and will continue learning.
Thanks again.
