• WiFi server for web setup of credentials and geographic data (no need to reprogram the controller every time).

• Improved icons (night icons are displayed with a moon symbol instead of a sun).

• Updated display layout for improved readability (optimized for LilyGo 2.13" 250x122 e-Paper display).

• implemented battery check.

• Popup messages for WiFi, battery, weather server, or time sync errors.

• Fast partial screen refreshes

• Popup greetings feature: displays a recurring message every year on a set date (e.g. birthday greeting).

Housing 3D model

• The STL design files for 3D printing the housing are included in this repository. This design is based on Sir.Puchtuning's project, with added feet and reinforced, optimised structure for 3D printing.
• The housing can fit a 1000mAh 3.7V battery.
• The front cover can be screwed by M2x10mm screws
• the back part of the feet needs to be attached by glue (separated this way for better printability)

Setup server

The web interface enables setting up credentials, time zone, api key, etc. without reprogramming the controller.

Usage: For entering the Weather Station Settings page keep the "next" button pressed while switching the power ON. This will start a WiFi server called "weather_station_wifi". Connect to this and open http://192.168.4.1/

The values will be stored in the EEPROM permanently (even after power loss). Erase using: http://192.168.4.1/erase_eeprom

Popup messages

To set up a yearly recurring popup message (up to four), open the (hidden) popup setup page while in setup mode:

http://192.168.4.1/popups

This will show your greeting message every year on the set date:

Notes

• The default screen refresh period is set to 60 min. The controller is in deep sleep in between. This enables battery life for a couple of months using a 1000mAh 3.7V battery.
