Where each one falls short

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

August Smart Lock

  • One-time purchase model with no recurring subscription fees
  • Smart locks range from $129.99 to $229.99 depending on model and features

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
