+'mysa2mqtt': patch
+---
+
+Refresh the supported hardware table in the README.
+
+Several rows had drifted from the code: V2 (non-Lite) thermostats did not mention that their power figure is an
+estimate derived from the duty cycle, in-floor thermostats gained ambient/floor sensor selection, and AC thermostats
+gained fan-speed control. The ⚠️ markers and "in progress" wording described those caveats as pending work rather than
+as characteristics of the hardware, so the supported families are now marked ✅.
+
+Central-HVAC thermostats (`ST-V1-0`) are listed for the first time, as not supported: they talk to the cloud over AWS
+IoT Device Shadows instead of the protocol every other family uses. The row links to the tracking issue and to the
+capture instructions, for anyone who owns one and wants to help.
