Denon AVR and Remote3 following a power outage

General
1

We had a power outage here, and when everything came back online the Remote3 has been unable to get in touch with my Denon AVR and all activities involving it fail to launch.

I’ve tried to re-run the configuration and reset it. But nothing seems to stick, and the remote refuses to connect to the AVR again. The remote finds the AVR during the re-configuration but when looking at all the entities they show up as “Unknown” carrying no data, resulting in no activities working.

Has anyone had similar issues and found a fix?

Hi, maybe a silly suggestion but did you try to turn on the avr manually one time and then reboot the remote?

Yup. Tried the following:

  • On/off the AVR
  • On/off the network connection on the AVR (static IP)
  • Rebooted the Remote3 about seven times

Nothing seems to stick sadly.

Are you sure, your AVR still has the network-connection after that?

Searching for “Denon AVR network after power outage” brings this:

“After a power outage, the Denon AVR often loses connection.”

It shows up on my list of connected devices when looking at my routers interface. And when I run the re-configuration process on the Remote 3 web interface it finds the AVR.

Edit:’

For the sake of it, I enabled DHCP on the AVR again, it got a new IP address, and re-configured on the Remote 3, and comfirmed it was the new IP. Same issue persists after rebooting the remote.

Can you screenshot the integration page for the denon please?

And now everything decided to start working again for some reason. Hopefully it sticks this time.

Not that this should be the cause of your pain but you are on version 0.14.0 and current version is 0.17.0. Are you using the R3 beta software?

Not in the beta.

I don’t want to run not-final stuff on the remote, as it’s far from popular in the house and I don’t want to rock the boat further.

Understood but their beta channel has been stable for some time now.

Can I ask what model is your Denon A/V?

it’s a long shot but I had network issues with mine after a power outage, and it turns put the network chip on my model can be defective and drop network connection randomly, I had to service it and teplace that part of the board…

(Mine is an X3800H)

Same model as yours.

Everything started to work again after a day and a half, so I don’t know if there was a cache somewhere that needed to fix itself.

:crossed_fingers: you don’t go through the same issue I had :stuck_out_tongue_winking_eye:
