Is it possible to use a DHCP option 42 (NTP server) in the home assistant DHCP server? I’ve added chrony to my installation and would like my clients to use this.
I assume you mean the DHCP addon?
Possible? definitely.
Easy? Depends on your knowledge.
You’d have to enter the DHCP docker container and edit /etc/dhcpd.conf to add a option ntp-servers line.
Good idea @koying! 
Hadn’t thought I could do that. I’ll read up on HA docker access.
…and yes, I meant I’m using the DHCP Add-On and the Chrony Add-On in Home Assistant.
