etersky 3 led clognote

Question

Accepted Answer

Direct answer to the question - Three LEDs blinking simultaneously on an Etersky roller-shutter or curtain switch almost always means the unit is in pairing configuration mode and is waiting to be added or re-added to a Tuya-compatible app such as Smart Life or the proprietary Etersky app. - Fast blink ≈ “EZ” mode quick pairing via broadcast. - Slow blink ≈ “AP” mode pairing through the device’s temporary Wi-Fi hotspot. - If the three LEDs stay solid ON not blinking after power-up and do not respond to a reset, the internal electronics are generally considered faulty and the switch must be replaced. Key points • 3 LEDs blinking → device not yet associated or has lost credentials. • Complete a reset, then pair on a 2.4 GHz Wi-Fi network through the app. • After pairing, perform motor calibration; LEDs should stop blinking. • Persistent solid LEDs with no response = hardware failure. --- Detailed problem analysis 1. LED signalling logic latest EterskyTuya firmware • Fast triple blink ≈2 Hz: EZ pairing mode – the switch is broadcasting and waiting for the app to discover it. • Slow triple blink ≈0.5 Hz: AP pairing mode – the switch has created a hotspot called “SmartLife-xxxx”. • Single LED blink during movement or after pairing: stroke travel-time calibration pending or running. • No LEDs or unlit keypad: no mains or neutral missing. • All LEDs permanently on: µC watchdog fault or TRIAC driver short – treated by the manufacturer as non-repairable. 2. Why does it enter pairing mode? • First power-up after installation. • Accidental long-press of centreSTOP key ≥5 s. • Loss or corruption of stored Wi-Fi credentials router change, SSID renamed, factory reset. • Flash update failure rare. 3. Sequence to restore normal operation a Safety first: isolate mains before touching wiring. b Soft reset 5 s press – LEDs start blinking fast. c Open Smart Life Etersky app ➔ “+” ➔ Electrician ➔ CurtainBlind Switch. d Enter 2.4 GHz SSID & password ➔ wait ≤60 s. e If the app fails to discover, switch to AP mode: long-press again ≈10 s until slow blink ➔ let the phone connect to “SmartLife-xxxx” hotspot ➔ return to app. f Once displayed, rename device, set location, update firmware if prompted. 4. Mandatory calibration otherwise you keep a single blinking LED • Via hardware: hold UP ~5 s until only UP LED flashes ➔ drive shutter fully open ➔ press STOP, then drive fully closed ➔ STOP ➔ hold STOP 5 s to save. • Via app: Settings ➔ Calibration ➔ follow on-screen instructions motor will run full cycle automatically. LEDs extinguish or return to steady back-lighting after a successful calibration. 5. Cases where pairing succeeds but LEDs keep blinking • Wrong neutrallive wiring device powered through motor lines only. • Wi-Fi signal 30 mA at idle often signals a shorted snubber or TRIAC. --- Current information and trends - All current Etersky wall modules use a Tuya TYWE3S or CB3S Wi-Fi SoC with the standard 2022-02 “TYSR-Curtain-v1.8” firmware, keeping the LED code described above. - Matter-over-Wi-Fi support is planned announced Q4-2023 but not yet present in released firmware; LED codes are expected to stay identical. - Community firmware e.g., Tasmota 13+, ESPHome allows custom LED behaviour, but re-flashing voids warranty and must be done before installing to mains. --- Supporting explanations and details Technical rationale - LEDs are multiplexed through the same GPIO expander that handles capacitive touch; firmware cannot drive complex patterns without entering a dedicated loop, hence “all blink” is reserved for a limited set of states primarily pairing. - Calibration is purely time-based; because no positional encoder exists, the controller must know the motor run-time to calculate %-open. The firmware flags an uncalibrated state by flashing the last button pressed. Example scenario Router exchanged for a Wi-Fi 6 model on 5 GHz only ➔ switch loses 2.4 GHz beacon ➔ after two failed reconnect cycles, firmware clears credentials ➔ enters EZ pairing → triple fast blink. --- Ethical and legal aspects - Mains-voltage work is subject to national wiring regulations NF C 15-100 in France, BS 7671 in the UK, NEC in the US. Only qualified personnel should remove the switch from the wall box. - Devices must carry CEUKCA marks; altering firmware may void these approvals. - Respect GDPRprivacy: Tuya cloud servers are outside the EU; for sensitive installations consider local-only firmware. --- Practical guidelines Implementation checklist 1. Kill breaker, verify absence of voltage. 2. Pull switch; confirm tight screw terminals, no copper exposed. 3. Restore power; observe LED rhythm: – Fast ≈2 Hz ➔ add via EZ. – Slow ≈0.5 Hz ➔ add via AP. 4. After inclusion, run calibration immediately. 5. In app: disable “indicator light” if unwanted at night. Potential challenges - Dual-band SSIDs with identical names confuse 2.4-only devices; temporarily disable 5 GHz or create separate SSID. - Some fibre routers use DFS channels 12-13; the ESP8266 inside TYWE3S cannot connect; pin router to ch 1-11. --- Possible disclaimers or additional notes - The LED codes above apply to 2020–2024 Etersky models; earlier RF-only controllers used different patterns. - A very small batch Aug 2021 had a bootloader bug that produced continuous fast blinking even after pairing; vendor swapped units under warranty. - If the shutter motor draws >2 A at stall, the internal TRIAC can fail with LEDs stuck ON; no user-serviceable parts inside. --- Suggestions for further research - Monitor switch traffic with Wireshark to verify MQTT traffic stability. - Evaluate replacing cloud firmware with ESPHome to integrate natively with Home Assistant and maintain local control. - Investigate predictive maintenance: measure motor current during every run and flag rising consumption indicating mechanical wear. --- Brief summary Three blinking LEDs on an Etersky smart roller-shutter switch are a firmware code for pairingconfiguration. Reset the device 5 s press, add it to Smart Life on a 2.4 GHz network, then calibrate the motor travel. Blinking stops once both steps succeed. Persistent solid LEDs or no response point to hardware failure requiring replacement.
