Been in IT for over a quarter century so your mainframe story resonates 
I do have Rachio sprinklers and a MYQ garage opener but they aren't being used in Hubitat. I have not integrated them yet (the MyQ requires a bit of work plus apparently the native sensor doesn't work). No ACs though I do have Honeywell smart thermostat that's been in operation for over 5 years--that's not integrated yet either.
I doubt anyone in my neighborhood has any smart devices. I am in the Middle East 
They are all on a different Zwave frequency, even if they do have some devices in use. I have stuck with my NA devices. This is actually why I purchased the C7 because I wanted to start moving to Euro ZWave bulbs. It's become awfully difficult to get 2700K ZWave bulbs in the US.
Edit: It seems like Hubitat has issued an advisory about the Zooz plug I am using though I doubt it has anything to do with the issues I have. I am gonna check the firmware version to be safe.
