Charge management broken with DNS TTL 0 #319

Closed MattiasTF closed 3 months ago

MattiasTF commented 4 months ago

If a charger is configured with a host name and the DNS server responds with a TTL of 0, cm_mdns keeps resolving the hostname but we never send any data to the charger.

Consider patching the IDF’s lwIP to raise the minimum TTL of responses to 10 or 30 seconds.
