Although I appreciate the effort that went into taking this project to completion, I have found it basically useless for me. I previously had a somewhat similar product made by Parrot that worked very well for years. Unfortunately, when the sensor went out, Parrot no longer supported the product. I supported this project and purchased a 10 sensor package. Of the first 5 sensors I set up, 2 didn’t work. Of the 3 that worked, 2 were on similar plants. There was no way to differentiate the 2 plants as their names could not be modified and, although I replaced the apps stock photo with individual photos of each plant, I would find the personal photo replaced by the stock photo every day. When setting up the remaining 5 sensors, I kept getting readings that didn’t make sense to me so I took 3 of them and placed them next to each other and got different readings from all of them by a large margin. I gave up at that point.
