I receive this command since a while. Rebooting the remote helps but it is super annoying. Does anybody have a similar issue?
Without logs it’s impossible to help you. Go to settings/development/logs and choose core service and the matching integration that is used when you get this error right after the error appeared. Use a site like pastebin.com to upload the logs.
Keep in mind that if you haven’t enabled prevent sleep in you activity the remote needs some time to reconnect all network devices after it wakes up from sleep. And if you haven’t enabled keep WiFi connected in standby in energy saving settings this takes even longer. On the remote itself under settings you can also enable an option to retry sending a failed command for a specific time. Unfortunately this doesn’t work for activity on/off sequences yet.
