✅ - Works<br>
❓ - Not tested<br>
❌ - Not implemented<br>
❗️ - Broken<br>
⚠️ - Warning<br>
➖ - Not applicable<br>

¹ Success dependant on partition layout set in bootloader. SPI flash QIO firmware for guaranteed OTA success<br>
² Excluding 1MB variation<br>
³ Implemented, but no tool to generate the file<br>
⁴ No HTTP OTA, only in Web App<br>
⁵ OTA attempt leads to device crash<br>
⁶ Web App OTA is broken, use HTTP OTA<br>
⁷ Software PWM, expect flickering<br>
⁸ Be careful with pin assignments, some PWM channels overlap<br>
⁹ WDT is configured in SDK<br>
¹⁰ Timer sleep only, no GPIO wakeup<br>
¹¹ After waking up device will refuse to connect to WiFi until power cycled<br>
¹² Only in _ALT builds<br>
¹³ Must be manually enabled (CONFIG_ESP8266_WIFI_ENABLE_WPA3_SAE/CONFIG_ESP_WIFI_ENABLE_WPA3_SAE to y in sdkconfig.defaults)<br>
¹⁴ OTA on Tuya BK7252 is not supported (stock bootloader won't do anything, custom won't encrypt main partition on unpack, bricking it)<br>
