Thank you very much for your comments. They were very helpful, I learned a few things and also I was able to correct the problem after selecting the desired initialize Pin State.
Your comment about the choices for Deploy is also interesting. I did not realize that simply pressing "Deploy" actually restarts all the flows.
While the fix you proposed solved the problem I initially described, I have a related problem that you may also be able to help with.
Another flow I created sends me a text message every time my sprinkler system starts or stops. (I am using Shelly-1pm puck to control my sprinkler actuators via MQTT.) If I press the Full Deploy I will always get a text message. However, if I select the "Modified Flows" Deploy as you suggested, a text message no longer gets sent. I am wondering if there is some other way to eliminate getting these unwanted text messages other than using the "Modified Flows" Deploy (which is a good work-around).
Again, thank you for your help!
