The IFTTT authorization process is not working from IFTTT. So, there is no handshaking between EDYN and IFTTT so to speak. I have been working with EDYN to address this issue and we narrowed it down to a IFTTT issue. However, I am super pleased with the EDYN sensor (in fact i just purchased another one) and the main purpose i want to use the Rachio to EDYN integration is for watering adjustments based on environmental factors such as moisture saturation, humidity, light, temperature, and even nutrition levels. For me it is important because one of my zones runs a hydroponic garden inside my greenhouse were the climate is different. I would start small of course (such as if moisture % is below X, then water Y. - IFTTT does have this applet but who wants depend on them, especially since they dont respond to tech support cases most often). Being a system integrator myself, i would share/assist in anyway possible to have direct Rachio to EDYN API integration.
