Hi @ModLogNet I think this script is not well polished enough, and people should take extra precautious when using, so I'm reluctant to make this a proper repository, maybe you can create your own gist for BX4 and we can link each other's gist so that other people can find them :). But I've made it public just in case your BX4 change is also compatible with BX1, then you're welcome to update this :)
@Tmbao You are a legend, I had my device running in 5 minutes with this. Spent ages trying to get it running with Tuya ble to no avail.
Interestingly the MAC address reported in the Holman app for me wasn't the true peripheral BLE Mac Address - I managed to sniff it with a Nordic sniffer to find a slightly different address. App reported C7:34:2C:92:10:38 but the working MAC for this was f8:10:92:2c:34:c7 (reversed order and different start byte)

Hi I'm adapting this to work with the BX4's as well, I noticed that you have this listed as private, would you prefer I not release my changes?
