That ibs-m1 thing is a little gateway device that links i believe up to 8 individual temp/rh sensors into the app for monitoring and those sensors also have a spot for a plug in probe for monitoring soil temps! Actually forgot all about them things til just now! May need to see if outside my bedroom window is too far away from the device for a sensor to work cuz would def help monitoring the overnight soil temps for the cucumbers!
