FAQ
TL;DR: Users reported 0.2–0.5 s touch delay on a 4‑way BK7231T wall switch; “its state will change after about 0.2sec to 0.5sec.” This FAQ compiles fixes and Alexa setup discussed in the thread. [Elektroda, omidjozani, post #20436469]
Why it matters: It helps OpenBeken users quickly remove touch lag and get reliable Alexa discovery on multi-gang switches.
Quick Facts
- Enable Flag 6: Instant touch reaction (aka SetOption 13) to trigger on press, not release. [Elektroda, p.kaczmarek2, post #20436919]
- For Alexa discovery, start both SSDP and Wemo drivers: backlog startDriver SSDP; startDriver Wemo. [Elektroda, p.kaczmarek2, post #20441379]
- Startup commands run only at boot; use console for immediate one-time execution. [Elektroda, p.kaczmarek2, post #20440959]
- Current Wemo multi-switch emulation is not fully ready for multiple channels. [Elektroda, p.kaczmarek2, post #20441983]
- Reported setup: 4‑gang switch, BK7231T chipset, WB3S module, firmware 1.15.419. [Elektroda, omidjozani, post #20436469]
How do I fix touch latency on my OpenBeken 4‑gang BK7231T wall switch?
Enable the Instant touch reaction feature. In OpenBeken, turn on Flag 6, which maps to SetOption 13. This changes behavior to switch on press rather than on release, eliminating the perceived delay. Users reported that enabling it resolved the issue instantly. “Instant touch reaction instead of waiting for release.” [Elektroda, p.kaczmarek2, post #20436919]
Where exactly do I toggle Flag 6 (Instant touch reaction)?
Use the OpenBeken Web UI Flags page and enable Flag 6: [BTN] Instant touch reaction (aka SetOption 13). Save and test your touch pads. This removes the release wait, so the relay toggles on press. If you prefer console operations, use the corresponding flag control documented for the firmware. [Elektroda, p.kaczmarek2, post #20436919]
How do I add my OpenBeken switch to Alexa?
Use Wemo emulation with SSDP. In the console or startup commands, run: backlog startDriver SSDP; startDriver Wemo. Then run discovery in the Alexa app. “Wemo relies on SSDP discovery.” This combination lets Alexa find the device as a smart switch on your network. [Elektroda, p.kaczmarek2, post #20441379]
Alexa still doesn’t see the device after I set Wemo. What did I miss?
If you added startDriver Wemo as a startup command, it only executes at boot. Restart the device so the driver loads. Alternatively, enter the command in the console to run it immediately one time. After that, perform device discovery in the Alexa app. “It only executes on startup.” [Elektroda, p.kaczmarek2, post #20440959]
Alexa found only one switch on my 4‑gang device. Can I expose all channels?
At present, multi-channel emulation is not fully ready in OpenBeken. Alexa typically discovers a single on/off entity. The developer noted this is on the priority list and asked for testers. “Multiple switch mode is not fully ready yet.” Watch project updates for multi‑gang support. [Elektroda, p.kaczmarek2, post #20441983]
How many channels does Alexa recognize today on a 4‑way unit?
Users reported Alexa recognizes it as a 1‑way switch controlling only the first channel. The other channels are not exposed through current emulation. This is consistent with multi‑channel support status and is being tracked for improvement. Expect one controllable channel out of four until updates land. [Elektroda, omidjozani, post #20441834]
What’s the recommended way to integrate with Home Assistant?
Use OpenBeken’s automatic Home Assistant discovery instead of manual YAML. The developer explicitly asked about using auto-discovery, which avoids entity duplication issues. If you already copied YAML from the device page, consider replacing it with discovery for cleaner setup and unique entities. [Elektroda, p.kaczmarek2, post #20451318]
My second and third 4‑gang YAML configs control the first device. How do I fix it?
Switch to automatic Home Assistant discovery. The developer requested the YAML to diagnose, and recommended auto-discovery. Manual YAML can be error-prone for multiple identical devices. Using discovery ensures unique identifiers and correct device mapping without manual duplication. [Elektroda, p.kaczmarek2, post #20451318]
My switch hung with Wi‑Fi LEDs solid and stopped responding. What helps?
One report described a hang where only Wi‑Fi LEDs stayed on. A power cycle restored normal operation. Capture circumstances if it recurs and share details to aid development. This edge case appears rare but is worth monitoring after changes. [Elektroda, omidjozani, post #20451255]
Which hardware and firmware versions are referenced in this thread?
A 4‑way wall touch switch using the BK7231T chipset with a WB3S Wi‑Fi module was used. The firmware reported was OpenBeken 1.15.419. These specifics help replicate behavior and verify fixes like Flag 6 for touch latency. [Elektroda, omidjozani, post #20436469]
Is Hue Emulation available, or only Wemo, for Alexa?
Community members are awaiting either Wemo multi‑device capability or Hue Emulation in OpenBeken. A workaround thread exists, but recent Alexa app changes complicate detection. Expect updates from the project as integration evolves. Consider temporary alternatives while multi‑gang emulation matures. [Elektroda, jkwim, post #21303254]
How do I enable Instant touch reaction? (3‑step How‑To)
- Open OpenBeken Web UI and go to the Flags page.
- Enable Flag 6: [BTN] Instant touch reaction (aka SetOption 13).
- Save and test a single tap to confirm immediate state change. [Elektroda, p.kaczmarek2, post #20436919]
