This is a bit of ‘hillbilly’ tech 
however you might have a look at this BLE device, as it ‘meats’ your no soldering requirement. Would require a ESP32 device (maybe not need the esp32, as the ‘theengs gateway’ might be able run on your Home Assistant server if it has a available and accessible BLE adapter, however I like keeping my HA server as simple as possible so the ESP32 route) to translate the BLE to MQTT or HA API’s but that gives you range extension options as well. And this device has local display, multiple inputs and fairly low cost. Good hunting!
