esp8266-arduino-ebus

connect adapter to ebus
you should see at least one LED on the adapter shining (HW v3.0+) - if not, switch eBus wires
search for WiFi networks, you should see network with name "esp-eBus"
connect to the network - a configuration page should open automatically
configure your WiFi network settings (SSID, password)
after reboot, you should be able to run ping esp-ebus.local successfully from a computer in your network (if your network is correctly configured for mDNS)
LED D1 blinking indicates activity on the bus. The adapter comes pre-adjusted but if D1 is still on or off, you need to re-adjust it using trimer RV1: turn the trimmer counterclockwise until you find the position between D1 blinking and still on turn the trimmer clockwise until you find the position between D1 blinking and still off count the turns between these positions and set the trimmer in the middle position with D1 blinking
the adapter listens on following TCP ports (latest SW): 3333 - raw - on this port you can both read and write to the eBus - ebusd config: -d esp-ebus.local:3333 3334 - listen only port - everything sent to this port will be discarded and not sent to bus 3335 - enhanced protocol - ebusd config: -d enh:esp-ebus.local:3335 5555 - status server - you can telnet to this port (or http://esp-ebus.local:5555) to see some basic status info
to verify there are bytes being received by the adapter connect to esp-ebus.local port 3334 using telnet - you should see unreadable binary data
you can use ebusd to decode bus messages, see ports section for device option configuration
