iHome motion sensors and door window sensors

I have a number of iHome motions sensors, iSB01, and door/window sensors, iSB04.
I was using IFTTT to bridge them to Home Assistant.
Recently, iHome dropped Android support for iHome devices, so they’re useless to me.

I was wondering if anyone had had any success in flashing the firmware on these so they could be used with SmartLife or some other app.
