My IoT Cloud project works well using a MKR WiFi 1010, MKR ENV Shield, PIR sensor and IoT Remote IOS app on an iPhone X, but the Messenger widget's operation is still a bit of a mystery. At first I had one Messenger widget displaying different messages when two different variables changed. I ran into intermittent problems that went away when I defined two different Messenger widgets and linked them to the two separate variables.
Is there more detailed documentation on how the Messenger widget operates? If so, I haven't been able to find it and it's not well-described in the tutorials. It seems that one widget can only be linked to one variable at this point. I know that you cannot link across sketch "Things" at this point without using the API but this is within the same sketch.
Thanks for your offer of help, ubidefeo, but figured out the messenger widget problem. Attached are the sketch and screenshots of the Things and Dashboard since they might help someone else. I learned a lot from this project including remote environmental data monitoring, integration of a smart phone with IoT Cloud using the IoT Remote app, acquiring timezone-adjusted timestamps via the IoT Cloud, remotely activating low and high power devices with my iPhone and IoT Cloud, and using the messenger widget for two-way communication between the IoT dashboard and Arduino MKR 1010 .
