Love using this, but every 2 or 3 days the buttons stop working and says “Error Sending Command”. Done this since the beggining. Ive searched the problem before, and ended up setting up hubitat on its own dedicated IP. What else could be wrong? I have internet coming in to a cable modem. Then ethernet from cable modem to a new netgear wifi router. My hubitat is connected to the router.
Does the cable modem set an ip number for the router and sometimes that changes and screws everything up?
Welcome to the community and sorry to hear that things intermittently aren’t working as expected.
Setting the Hub IP to a fixed local IP address is a best practice, so that’s a good start. How do you ‘fix’ things when the issue starts? Does it resolve on its own or you have to manually reboot the hub or something else?
Weird. Definitely sounds like a deeper rooted problem.
Are you using any other cloud connected services like Google Assistant, Alexa, or IFTTT? If so, I would suspect that those would fail at the same time.
Sounds like the hub might be hanging or somehow not able to connect network for some reason until a reboot was made. Did this just happen recently? Are you aware of any recent device/smartapp added to the hub?
That’s a different error and means the API Key on the hub for communicating with SharpTools is invalid for some reason. Last time it seemed like your hub was having some pretty fundamental network issues periodically. Reauthorizing your Hubitat hub starting from your SharpTools.io user page → Manage Connections should get a new API Key issued.
Edit: If you are still having fundamental network issues with the hub, then you may not even be able to authorize things. If that’s the case, getting in contact with Hubitat Support about the broader hub network issues and getting those resolved would be the first step.
