Some years ago I bought 4 large 7-segment display SA40-19SRWA and now I found the best controller ESP32 to get the time from NTP and the temperature via MQTT from my home automation server. So I build a system with 3 components:
1. Sensor modul based on ESP32 and DHT22 sensor.
2. HAS home automation server based on RaspberryPi and MQTT.
3. 4 digit display with large 7 segment modules and ESP32.
