Hi Ray
Thanks for your comments.
I don’t think SmartSolenoid can be considered in any way competitor of your OpenSprinkler products.!
First of all it is Bluetooth and you don’t have any Bluetooth product, second it is not a controller but is a solenoid embedded BLE micro to drive wirelessly a single valve.
So in reality is more an integration to create a new family of controllers that will operate remote valve’s without the need of any wire!
As a matter of fact your firmware ported to Esp32 is already a powerfull controller of valve’s without the need of any additional hardware so changing MCU you could easily transform your OS3.0 controller to become BLE enabled controllers!
You know I have ported OpenSprinkler to Esp32 : Esp32 OpenSprinklerand I can tell you that has been an easy task!
