Here is the odd thing: it works about half of the time. When I test with the RunActions button in Apps and look at the Live Logs, in the Apps rule Pushover works sometimes and fails other times with the message "DeviceNotification errorapi.pushover.net: Temporary failure in name resolution". IMO, cannot be the driver if it does work sometimes, right?
Thanks for the ideas, Mark. I am using Wi-Fi to connect my hub. I did see that using Hubitat with an ethernet cable to the router was the preferred method, but It was not discovering my Konnected boards so I went with Wireless. Do you think I should revisit the issues and switch to ethernet?
As @marktheknife has said, that message pretty clearly says that the Hub can't resolve "pushover.net" and send the message. We don't know how your home network is designed. I personally have complicated network with a LocalDNS that everything in my house uses first. You may have a very minimal network in which DNS is 'out there on the Internet'.
Assuming minimal, then your hub isn't able to reach your DNS because of a network or firewall issue.
One simple test is to use Settings: Network Setup: Network Test (up there on the top line) and use the Ping tool, by name. You hould see legitimate results:
Hello. I looked at the Network Setup page. The Ethernet Speed setting is just that, for Ethernet. I am using Wi-Fi for the Hubitat connectivity. Since the ping test fails about 50% of the time, it does seem like it may be a DNS issue. I have a Netgear genie C7000v2 with a basic out-of-the-box config. It's terribly frustrating; any other thoughts are greatly appreciated.
As a test, try using a hard-wired Ethernet connection between the HE Hub and the Netgear Router. The problem could be with WiFi connectivity/stability. At least this way you'll help narrow down where the problem is.
If it helps, great, if not, put it back
