Do you have a parental control rule without a mac address?

[jazzyisj]

Parental controls disabled on both router and HA.

[Vaskivskyi]

Please, update to version 0.27.1. Your issue should be solved now

Also, parental control rules are the ones set on the next tab. They are still saved in the device settings even if turned off. Apparently, one of the rules had issues with MAC address

[jazzyisj]

There was a rule under time scheduling. Must have been something that set up by default, I've never used that feature. I've deleted it and also updated. Error gone. That was fast, I feel like I've had my own on call personal bug fixer today! Asus Router keeps getting better and better! :-)

Happy New Year to you!
