Arduino library v0.1.1 September 16, 2026
Connection failures that say why
- A failed request reports its status with a reason — token rejected, no access, wrong host, rate limited, server error, or no connection — instead of a bare failure.
- A refused WebSocket handshake is reported separately from a dropped link, and socket errors are no longer swallowed. All of it behind
setDebug(true). - Installs from the Arduino Library Manager, the PlatformIO Registry, or the ESP Component Registry, with ESP-IDF instructions.
