[kanflo]

Blueprint name

Controller - IKEA E1743 TRÅDFRI On/Off Switch & Dimmer

Home Assistant Core Version

2022.4.3

Home Assistant Installation Type

Home Assistant Operating System

Description

Prior to 2022.3 long press on the E1743 worked like a charm using ZHA. Long press yields the following in the log:

Invalid value: {"trigger_action": "move_MoveMode.Down_83_bitmap8.0_bitmap8.0", "last_triggered": "2022-04-13 21:25:11.011648+02:00"} (length range 0 - 100)

To Reproduce

1. Long press up or down on the E1743

Expected behavior

The lights dimmed up or down.

Actual Behaviour

1. Devtools / States claims the automation has run
2. Configuration / Logs show an error setting the text input helper
3. Light brightness did not change

Additional Details

Additional context

Actually it seems a bit unfair to label this as a bug in this repo. The input text has a default max length of 100 bytes and this limit is two years in the making.

ZHA could be the culprit by suddenly creating longer events causing strings like this:

{"trigger_action": "move_MoveMode.Down_83_bitmap8.0_bitmap8.0", "last_triggered": "2022-04-13 22:47:23.227150+02:00"}

To regain dimming of lights, one first needs to bump the max length of the input texts (min might be optional):

input_text:
  johan_skrivbord_dimmer:
    name: Dimmer Johans skrivbord
    min: 0
    max: 255

Additionally, the automation needs to adapt to the new ZHA events. See #314

Side note: as 255 is the max input string length, it seems to me HASS is written in Pascal :smile:
