I’m moving devices from one network to another. From 192.168.1.0/24 to 192.168.40.0/24.
40.0/24 is a VLAN with its own WIFI SSID. If I modify the configuration for a device in ESPHome to have the new WIFI information then upload that information, the device takes on the new network settings, but all associated sensors become unavailable, like they don’t exist, despite a log that is receiving the information needed from the sensor.
Edit your device file and upload the new firmware.
Delete the device from Home Assistant (can be done before step one).
Add the device to Home Assistant.
I think that the step I was stuck on was having to manually add another device via IP in the integrations screen. For some reason, I thought that HA would notify me that there was a new device detected in the integration.
