[HELP] Evolvia 400 pairing impossible - no power button

Hardware

ESP32

Firmware version

v2.4.7

Application version

v2.4.7

What happened? What did you expect to happen?

I have an Evolvia 400 gate motor (Type 5063220A) with a Keytis 2-button RTS remote.
RX works perfectly - Radio logs show my remote (address 14319093, Toggle, 80-bit, -73dBm).
However, when I click PAIR SHADE, PROG, or Toggle in Virtual Remote, the RADIO LED on the motor never reacts. Nothing appears in Radio logs when sending = TX seems not working.

What I tried:

• Cover types: Gate 1-button center, Gate 1-button left, Garage 1-button
• Bit length: 56 and 80
• Addresses: 5000000/5065536 and 10663760/10729296
• Antenna physically touching the motor target
• GPIO 12=TX, GPIO 13=RX (verified correct)
• TX Power at max 12dBm
• Repeat Commands set to 5
• Short and long press on Toggle in Virtual Remote

Important: my Evolvia 400 has NO power button on the board, only LED indicators. S.ATUT LED is always red = motor active.

Pairing with real remote works fine: place remote on target, short press button 1, RADIO LED lights then off = paired.

Expected: RADIO LED reacts when ESPSomfy sends PROG/Toggle signal.

How to reproduce it (step by step)

1. Create a cover: Gate 1-button center, 80-bit, address 10663760
2. Go near the gate motor, place ESP antenna on the target
3. Place real Keytis remote on target, short press button 1 → RADIO LED lights then off = motor in pairing mode
4. Immediately click PAIR SHADE or PROG button in ESPSomfy
5. RADIO LED never reacts → pairing fails
6. Also tried Virtual Remote → Toggle (short and long press) → same result

Logs

Radio logs show Keytis remote correctly:
164  14319093  Toggle  12376  -79dBm  80-S
164  14319093  Toggle  12376  -81dBm  80-S
164  14319093  Toggle  12375  -75dBm  56-S

No log entry appears when clicking PAIR SHADE or Toggle in Virtual Remote = ESP does not seem to transmit anything
