Interactive API guide

Learn the API by running it live. Cloud API development walks the steps through the cloud (login, controllers, decoders, programs, log); Serial development runs the controller’s command set straight down an RS232 cable.

Serial (RS232) — connect

Chrome/Edge only. Because this page is served over https (a secure context), the browser can open a COM port directly — like PuTTY. Close PuTTY first: only one program can hold the port. The serial data never leaves this machine.

Line ending (sent on Enter/Send)

Advanced framing (default 8-N-1)

Terminal

Live view of everything sent (» lines) and received. Type a command below and press Enter to send it by hand — like PuTTY. The steps further down write here too.

Connected straight to the controller, so there's no login. Each step sends its command down the port and shows the reply underneath; step 1's reply fills the address dropdown that step 2 reads, and step 3's ts/rt feed step 4. Steps 5+ cover the rest of the command set — TW (2-wire line), LU (decoders), WE (watering engine) and the compact/where params. ⚠-marked steps actuate real hardware. Commands are saved in this browser.
