I know it is recommended to use DHCP to assign an IP address to eisy and that is how I have my eisy setup. In my network gateway I run a DHCP server and there I added an ip address reservation for eisy. This worked really well up until the upgrade to v6.0.5. Since then the ip address on my eisy changes randomly every 15-20 minutes. Very weird... I would not be a big problem because I can get to the Admin Console using the ioX launcher but it breaks connection on the UD mobile app and Polyglot interface. Yes I can work around it but I have been told by my wife that I need to fix the app because it is currently "unusable" and "useless" as far as she is concerned.

Is eisy changing it MAC address dynamically and that is why the address reservation is failing? Can I just hard-code the ip address? I tried in the admin console under configuration but it will not allow me to unselect the "Automatic" and then set an IP address

It sounds like this would be more of an issue with the router. Especially since you configured a reserved DHCP address. When you look in your router's connected devices, does the eisy's MAC address stay the same, even when the IP address changes?

Is there a chance eisy is switching between wired and wireless or do you have a mesh system where eisy is changing acces points?

Initially I thought so but I have about 40 reserved ips and the only one changing is eisy. And I only saw this behavior once I updated to 6.0.5 about 2 months ago.

I have checked the router and at the time it did not show multiple mac addresses

It is hard-wired to the main router, so I am not sure if it is switching from wired to wireless but that makes sense. Yes, I do have a mesh network but as i said it is hard wired to the main router so i do not thing it is swithing nodes and it is within 4 ft of the router. I will look further into the switching from wired to wireless. Just not sure why it is doing it now.

If your router has logs I would look there. You might have to raise the log level to see each DHCP address assignment. Wait for it to happen again and go look there.

The answer should be there. The factory MAC address for the EISY should be on it's case for reference.

If you ever setup the wifi then it is still in there and it will obtain multiple ip addresses. It used to be you press the multi function button 4 times to reset the wifi. You should be able to see in your router what kind of connection an ip address is using so I think this is going to take some investigation on your end to see exactly what is happening.

You may want to disable wifi completely.

Open an SSH session, and use this command:

sudo udxops.sh wifi.disable

Thank you. I did this and will monitor the system over the next couple of days
