Hisense tv mqtt ip control

Third party integrations
1

Hi everyone

I’m trying to integrate my Hisense 75A7HAU TV (VIDAA U6 firmware V0000.06.12X.N1212) with HA for IP control via MQTT, but sending commands isn’t working.

What works:

• Connected to MQTT broker on port 36669 (hisenseservice / multimqttservice, Client ID from paired VIDAA app).

• Monitoring is perfect — I see real-time events in MQTT Explorer (volume changes, app state, etc.).

What doesn’t:

• Sending commands (volume up/down, power on/off, input switch) — payloads like {“key”:“KEY_VOLUMEUP”} or {“action”:“sendkey”,“key”:“KEY_POWER”} are logged in history but do nothing on the TV.

Tried:

• Client cert/key from the Hisense-mqtt-keyfiles GitHub repo

• Validate certificate off, mqtts, various nested payloads

• Different MACs in topics

Hisense support confirmed no official third-party IP control.

Any working payloads/topics for sending control on VIDAA U6? Or is it read-only on this build?

Thanks!
