Firmware

WM-2.3.4.bin

  • Fixed an issue where the reading angle setting was not applied correctly.
  • The default reading angle has changed from 16° to 27°. If you experience level-reading issues after the update, adjust the angle until the measurement is correct. Reliability increases with the reading angle, but the maximum usable angle may be limited by obstacles such as the tank walls and float. See the Angle Water Meter page.
  • Improved device startup-delay management for more reliable reconnection at power-on, such as after a power outage. By default, the device now waits 3 minutes at startup for the WiFi network to become available again.
  • Fixed an issue where level readings returned nonsensical values in the event of an incorrect configuration when viewed locally. This bug did not affect the cloud service.
  • Improved device reliability during extended use.

  • The message sent by the device now also includes the local IP address.

Firmware

WM-2.2.0.bin

  • Added support for the new ET-VL V2.1 revision.
  • ET-VL V2.1 improves the sensor initialisation process after a software reboot; on ET-VL V2.0 the same effect is achieved with a full reboot.
  • Added the RESET WIFI function to restore the WiFi configuration and return to AP mode.
  • Improved system readability: AP SSID WaterMeter-{ID}, nome host WaterMeter-{ID} e testo migliorato nella home.
  • Improved system stability while using the configuration portal.
  • Minor error, bug and performance fixes.

When upgrading from version 2.0.x to version 2.1.x or later, the Water Meter and WiFi network configuration will be reset. All local configuration must be set again and the WiFi connection must be reconfigured after the update.
