+## 0.2.97 (firmware 0.2.83)
+
+Two diagnostics for the Elecrow's touch bus, callable from Home Assistant.
+
+- **`touch_probe` and `touch_reset` on an Elecrow.** Two actions of the screen (Developer tools → Actions, `esphome.<screen>_touch_probe`): the probe logs the PCA9557's four registers and whether a GT911 answers at 0x5D or 0x14 (its product id); the reset runs Elecrow's sequence with values of one's own (the expander's configuration during the reset, its outputs while the reset is held and after, the two waits, the configuration afterwards) and probes again. For a unit whose touch stays silent, without a new build for every try.
+- Needs firmware 0.2.83 on an Elecrow: press **Update** on the screen. Elecrow firmware: 1,867,584 bytes, 91.9 % of its update slot.
+
 ## 0.2.96 (firmware 0.2.82)

 The Elecrow's touch chip reset the way Elecrow does it.
