To make it work, you have to log into the s20 web page and configure 'devices' and 'rules' and create a rule that links the front button as a device to changing the state of gpio14, the relay/blue led eg Īt this point the front button doesnt do anything Now change ip address etc, device name etc if you wish - a fixed IP is necessary if you are sending commands from loxoneĪt this point you can send http commands from loxone to turn the device on/of - simple as that. I then used a desktop pc to continue the s20 configuration using a full screen browser with the new IP Pick your own home wifi and give it the password - it then gets a dhcp address from your router (make a note of the IP) Log in using a wireless device eg phone to the s20's own wifi access point and open a browser - you will get the s20 config page So i hooked up 2 x 1.5v AA cells to the s20 with a common 0v to the usb/serial adapter set it to 3.3v, and my other 3 s20 sockets were flashed in around 15 mins for all 3 from start to finish with the esp-easy firmware from windows. my usb adapter has a 5v/3.3v jumper, but after some white smoke i worked out it still puts out 5v when set to 3.3v - oops
#Loxone inc serial
Usb to serial adapters have 5v and 3.3v flavours - the s20 needs 3.3v. Ok so everything arrived and after 10 minutes i killed my first s20 in a puff of smoke!
