Do iSearching ST17H66B devices support OpenHaystack?

What I mean is, when the device is flashed with THB2 software and configured, can the device work in iBeacon mode, and/or can it be then added through an Openhaystack configuration?

I am just... sort of confused about all of this and wanted to inquire before ordering the devices. Or are these instead devices not intended for BLE advertising?

I am just trying to find very low cost devices, that come with cases, that I can use with OpenHaystack to act as DIY airtags. NRF51822 beacons on Aliexpress are expensive now, sometimes $9 per unit incl shipping.

I posted here too but maybe Discussions are a better space for this

There is no such firmware for thermometers. Only for key fobs with the ST17H66B chip. And then, it is necessary to clarify the device diagram. If the key fob has a different layout, then this will lead to greater battery consumption and the button or speaker may not work...
