v2.11

ESPHome 2026.1.4

v2.10

ESPHome 2025.8.2

BREAKING CHANGE
This version uses ESPHome's built-in friendly_name feature. Under some circumstances, this update could change some entity names to remove duplicative recitation of the device name.

v2.08

Update to ESPHome 2024.12.2.

v2.052

• early publish off by default (causes problems with larger loads, to be fixed)

v2.05

• ESPHome 2023.6.3
• Power monitoring early publish - When a power change exceeds configured thresholds, immediately publish sensor values instead of waiting for the next update interval. Default thresholds are +/- 3w or 25%.
• Reduced power monitoring timeout from 9s to 3s for better accuracy when power usage goes to 0.
• Allow networks: key for multiple Wi-Fi networks defined in yaml.
• Filter out power readings over 5000w (assumed error).
• Don't turn on LEDs when brightness changes.

v2.03

• ESPHome v2023.5.5
• Replaced light entities with switch and number entities. Reduces compile size so that main yaml can now be used with API encryption.
  • switch entities turn LEDs on and off
  • number entities control brightness.

v2.02

• Binary files built using ESPHome version 2022.11.5, but with custom components updated based on 2022.12.0b1.
• Rewrote HLW8012 implementation and renamed the component to kauf_hlw8012 to prevent confusion based on incompatible configurations between the stock and custom components.
• The new kauf_hlw8012 component removes the initial_mode and change_mode_every options. All sensors are now internally constantly updated as fast as possible and new values are published with the most recently read data every update_interval.

v2.00

• ESPHome 2022.11.1
• Additional power monitoring mode to report both current and voltage more often

v1.99

Adds a select entity to select boot-up state of plug's relay (restore, invert, always on, always off).

v1.98

• Button hold for 30s instead of 5s to force Wi-Fi AP. Forcing Wi-Fi AP is now done by overwriting stored or hard-coded credentials, so previous credentials will always be lost and Wi-Fi AP will always come up.
• Wi-Fi AP/captive portal is now included in yaml package as well as update bin file. AP will only enable if credentials are cleared through holding button for 30 seconds or through the web interface.
• Add GPIO substitutions to allow this firmware to be used with other ESP8266-based plugs with HLW8012 power sensor but different pinouts.

From Common components:

• ESPHome 2022.10
• Clearing Wi-Fi credentials and forcing Wi-Fi AP now both will write initial_ap/asdfasdfasdfasdf credentials to flash. The credentials saved in flash will overwrite any previous configured credentials and also take precedence over any credentials configured in yaml. Thus ensuring that the Wi-Fi AP will be enabled in almost any circumstance.
• AP Timeout is always shortened to 15 seconds if the software configured credentials have the SSID initial_ap.
• Reset flash storage using stock ESPHome function instead of custom function.
• Hard code an AP timeout of 15 seconds when Wi-Fi is not configured.
• In the captive portal, place focus back to password field after toggling “show password”.
