I have a related issue where I have tried to use the routers DHCP reservation feature but it gives an error that says the MAC address displayed on my OpenSprinkler 3.0 is an invalid MAC address (2C-3A-E8-08-11-4A). Looks ok to me so not sure why it doesn’t work but a real pain trying to find the correct IP address each time I need to access the Android app.
Also I have an OpenSprinkler Bee (I’m an OS fan boy!) and I cannot find the MAC address on this device and my router doesn’t report it but I would like to also fix the IP for this one as well.
Any Help much appreciated.
