I have this working.
I changed from sensors.getTempC - to - sensors.getTempF and that solved the problem. (I had an extra sensor here and built a circuit with a relay connected to test.)
I got the section with irrigation to verify but really don't have a way to test. Brother is gone to Italy for 2 weeks. Heat and vents are working and he has someone to come in and water so final testing can wait.
It gets to a point that you look at it for so long that you can't see the obvious. Another set of eyes can sure make a difference.
Thanks for your help!!!!!!!!!!
