Pixl.js control?

Hi,
New to both HomeAssistant and Pixl.js from Espruino.
I have 2 Pixl.js devices I had received long back and am wondering if there is a way to control certain functions of Home Assistant such as switching a smart bulb on/off is possible.
The Pixl.js supports Bluetooth LE and seems to have a Nordic nRF51/nRF52 chip?

Could someone point me in the right direction on how to connect with HomeAssistant, either via Bluetooth or via the Nordic nRF51/nRF52 chip, which seems to provide NFC capability?
I’ve figured out how to code on the Pixl.js, just can’t seem to make the connection to Home Assistant to access any APIs.
My Home Assistant is running on a Raspberry Pi 4 as the OS.

I would like to avoid soldering on a Arduino ESP8266 WiFi Shield to gain WiFi capabilities as I have no experience with soldering.
Thanks!
