I think you can adjust the scan interval in HA, if it is that important.
The scan interval of devices can be changed - true.
But not the behavior of DNS requests that comes with that - even with DHCP.
Meaning I tried to influence the caching as part of the DHCP request by giving the HASS server a âfixedâ IP address based on the MAC-address of the NIC.
Part of the DHCP request is DNS - which includes some caching timers. Tried to set these for 24-hrs - including the NX responses. It looks like HASS is ignoring these.
But if this caching thing is the âbiggestâ problem in my life I guess I can live with that⌠
The DHCP options you are talking about is only suggest time-to-live (TTL) values for that specific device that makes the DHCP request and only if the DNS service accept dynamic allocations.
Often the DNS server do not accept dynamic allocations and when it do it is even rarere to actually take those TTL values into account.
