Flash failed, successfully - possibly a TFT issue?

[beauzeaux]

I'm certain I've done something obviously wrong, I'm very rusty with embedded systems and very new to the esphome ecosystem so my apologies in advance.

Issue

I followed the setup instructions and everything seems to be on the happy path until I plug the panel into line power and it appears to load the Sonoff UI.

Oddly this doesn't appear to be the default first run experience for Sonoff (tested with a second untampered device) so flashing did something. I'm guessing these are the screens after performing the FRE setup, but I'm unsure.

ESPWeb flashing

Flashing appears to have worked fine.

Based on the discussions I'm guessing this is a fallback because of an issue with loading the TFT file.

Local nspanel matches the one on GitHub

I did find this discussion which sounds like a similar symptom but the solution to use the PR doesn't seem applicable anymore.

Any ideas or help would be greatly appreciated.

Go to the device's page (under Settings > Devices and Services > ESPHome), ij the configuration area, select your model and press "Update TFT".
Please share ESPHome logs if it fails.

Alright, I managed to figure it out!

I couldn't find the device in HA which wasn't surprising because it wasn't connected to the wifi! I had a valid SSID & password but I didn't realize the esp32 chips didn't support 5ghz! I swapped the SSID with the one for my 2ghz network, added the device in HA, and it is now in the process of updating the TFT!

I'd been staring at this for weeks, ty @edwardtfn - that suggestion got me on the right debugging path!
