Any suggestion to extend the Bluetooth LE range?
Thank you very much for the plugin. I've been using it and it works very well so far. I like the fact that it can publish temperature and humidity to MQTT Broker so that I can use those values in home automation.

However, I am experiencing the Bluetooth LE coverage range, which can't go to my second floor very steady. Do you have any suggestion on what I should do to that might help me extending the rage of Bluetooth LE of this device? Any suggestion would be worth for me to try.

Thank you in advance.
