Device: Aqara Light Switch H2 EU, double rocker (WS-K08E)
Firmware: Zigbee fileVersion 5658
Setup: Paired directly over Zigbee to a third-party coordinator (no Aqara
hub). Both gangs in decoupled mode, relays locked on.
Hi all — two related things about the H2 EU double rocker. Hoping for input from
Aqara staff, and curious whether other H2 owners see the same.
1. Upper rocker halves never send multi-press events
The two lower halves work perfectly and emit the full set of events: single,
double, hold and release. Holding one gives the expected pair:
hold_left_down -> release_left_down (held ~3s)
hold_right_down -> release_right_down (held ~7s)
The two upper halves only ever emit a single-press event, no matter how long
they are held:
single_left
single_right
No hold. No release. No double. I tested this across dozens of presses on both
upper halves at hold durations from under a second to roughly ten seconds. Not
one multi-press event was produced.
This appears to contradict the product documentation, which advertises
multi-press actions on the upper buttons.
2. The multi-click setting only exists for the lower halves
The device exposes a multi-click mode toggle for the lower halves only:
multi_click_left_down
multi_click_right_down
There is no equivalent for the upper halves. This is the part that makes me
think it is a firmware gate rather than a radio or pairing problem:
- With those two settings enabled, the lower halves emit hold/release
correctly.
- With them disabled, the lower halves stop emitting hold/release entirely —
every long press arrives as a plain single press, exactly the behaviour the
upper halves show permanently.
So the multi-press state machine is clearly gated by this setting, and the upper
halves behave precisely as if that gate exists but is permanently off — or was
never implemented for those endpoints.
Questions:
-
Is multi-press on the upper halves supported by the WS-K08E hardware at all?
-
If yes, which firmware version enables it, and is there an attribute
equivalent to multi_click_*_down for the upper halves that needs setting?
- If no, is it on the roadmap? And could the documentation be corrected in the
meantime, since it currently advertises the feature?
3. Firmware updates over standard Zigbee OTA
Related, and the reason I cannot simply test a newer firmware: as far as I can
tell there is no way to update this switch without an Aqara hub. The switch
reports fileVersion 5658 and no newer image is available through standard Zigbee
OTA channels — the widely used community OTA index has no entry for WS-K08E at
all, so a third-party coordinator has nothing to offer the device.
That leaves owners who run the H2 on a non-Aqara coordinator with no upgrade
path whatsoever. Unpairing, joining an Aqara hub, updating and re-pairing is
disruptive and means losing the device configuration.
Request: would Aqara consider publishing H2 firmware images for standard
Zigbee OTA, so devices paired to third-party coordinators can update normally?
Many other Zigbee vendors do this and it is a real differentiator for anyone
choosing hardware for a non-vendor-locked setup.
Question: is firmware newer than build 5658 available for the WS-K08E, and
does any released version change the upper-half button behaviour above?
Why this matters practically
With hold available on only one half per gang, there is a single hold-capable
button per light. Hold-to-dim has to drive both directions from that one button
— workable, but clearly not the intended design given the documentation. Full
multi-press on all four halves would make this switch substantially better.
Has anyone else with an H2 double rocker confirmed the same upper-half
behaviour, or found a firmware version where it works? Thanks.
