Cannot setup device on isolated wifi network

[bentemple]

Describe the bug

When powering the device after powering, device enters boot-loop if setup on a wifi network without internet access

Steps to reproduce

1. Flash factory firmware to device
2. Connect device to an isolated wifi network without internet access
3. Pair device to ESPHome in Home Assistant
4. Verify device functionality in HA
5. Unplug and re-plugin device power
6. Device enters infinite boot-loop

Expected behavior

Device should function normally

Environment

I've tried both the stock 0.4.0 firmware, and the latest 0.1.0-beta0
The wifi network I'm using is setup with a firewall to deny all wan, and all lan requests except for to my HA instance IP address.
I'm using an mDNS reflector which correctly allows other ESPHome devices to connect, chromecasts, and the new voice PE from HA also works and was setup successfully on this isolated wifi network.

Additional context

I flashed the factory image via the ESPHome web installer, connected it to an isolated network with access to my HomeAssistant server
I added the device in the homeassistant ESPHome addon and verified all sensors showed up normally
Unplug power and power again
Device boots up and then is "lost" Lights stay white and you cannot factory reset the device with the button.

[bentemple]

Quite possibly user error of course

[gnumpi]

Hey, thanks for reporting! It is probably related to a known issue in ESPhome which causes the device to reboot when a connection timeout occurs. The device checks for firmware updates on startups. I will bump to the newest ESPhome version soon, I think it includes a fix for this issue.
But, your issue reminds me that we need to improve our offline firmware update strategy!

[bentemple]

Was just looking into how I could standup the update server docker locally. Doesn't seem that hard but then I have to update the local url etc..

Sounds exactly like that esphome bug. And super excited to hear you thinking about that as good support for local updates will make me (and probably many other HA users) very happy.
