Nice, good working product. I've tested it a few days and works great. Seller is very helpfull, and will respond quickly to questions. I have no programming experience, and got it running fairly easy. Wil order more units in a few weeks.
I bought the system to beta test this soil moisture monitoring board to possibly tie into my commercial IOT platform. I currently have it running in my backyard monitoring my lawn moisture and triggering my sprinkler system. System works great. Board was easy to set up and program, and the seller, Rainer, was very helpful answering my technical questions. I am happy with the purchase and would definitely buy it again.
