Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Tasmota

  • Tasmota only runs on Espressif ESP8266, ESP8285, ESP32, ESP32-S and ESP32-C3 chipsets, so devices built on other silicon cannot use it
  • Initial installation requires opening the device, bridging GPIO0 to ground during boot and using a 3.3V serial programmer; a 5V programmer damages the chip
  • The ESP chip needs at least 150mA at 3.3V, so an underpowered supply causes flashing and stability failures
  • The Wi-Fi setup access point stays active for only 3 minutes, after which the device must be power cycled to try again
  • The Power Cycle Recovery feature can reset a device to firmware defaults where mains power fluctuates, and the docs advise disabling it in that case

TP-Link Kasa

  • Plus plan only covers one camera per subscription
  • No free trial mentioned for paid tiers
  • Premium plan requires annual commitment discount to reach $100/year pricing
  • Video retention limited to 30 days even on paid plans
