I would like to share my experience with Toro Soil Sensor and Iro:
Installation of both was trouble free - both devices are very easy to configure and integrate.
I am still learning Toro's moisture reporting (on screen) and optimum setup but having some interesting Iro's behaviour:
1. As soil sensor is configured by Iro as a rain sensor - I am getting not very obvious messages like "it is raining" or " it is not raining" when soil moisture is within or outside of the predefined limit. It would be nice to have a soil sensor selection in addition to rain sensor or an option to customise messages - especially of you want to expand to any international market
2. there is no info (also in v2) if the rain or soil sensor is blocking irrigation or not - this might be useful
3. I was trying to run the manual irrigation and the progress bar is moving but the irrigation does not start at all as it seems to be blocked by the sensor - this is a major issue as in some cases may want to override settings.
