is there OTA support?

[yvolchkov]

it turns out wifi is not working if Zigbee is on on esp32-c6. For me this ruins benefits of Esphome as I can't flash device over the air . Perhaps it is possible to switch off Zigbee on demand so device gets online in the wifi network and can be refreshed? Or maybe there is a way to use ota over zigbee with zigbee2mqtt? However the second is painfully slow, I would prefer switching back to wifi for the time of updating

Zigbee OTA would be cool, but is not planned at the moment.
Wifi coexistence should work since PR from @JochenFriedrich is merged: c806486
Please let me know if OTA is working with this.

That was exactly my motivation for this patch. esp_coex_wifi_i154_enable() does the trick.

Zigbee OTA wouldn't be easy at least for z2m as you would definitely need a custom converter with ota manually added to the automatic generated one. You also would need to track an 32bit upgrade_file_version which needs to be greater than the last uploaded one. And as you said it would take hours for a single update.
