Integrating a smart TV from Hisense on Home Assistant, using MQTT on your local network.

This is my successful experience getting this to work, with a TV Hisense H43B7320 and its firmware version V0000.01.00a.K0117.

Tested on Home Assistant Core version 0.111.4 and Mosquitto add-on version 5.1.

First of all, install the RemoteNow app on your android smartphone (https://play.google.com/store/apps/details?id=com.universal.remote.ms&hl=en). Pair the said smartphone with the TV, using the app. Save the mac address of this device for later.

You need to access the following path, having beforehand the Samba add-on installed on your Home Assistant instance:

• Windows: \\YOUR_HA_LAN_IP\
• Linux: smb://YOUR_HA_LAN_IP/

Put this inside a hisense.conf, in the above path - subfolder /share/mosquitto/. Change only the TV_IP_ADDRESS_CHANGE_IT_HERE, accordingly:

connection hisensemqtt
address TV_IP_ADDRESS_CHANGE_IT_HERE:36669
username hisenseservice
password multimqttservice
clientid HomeAssistant
bridge_cafile /ssl/hisense.crt
bridge_insecure true
bridge_tls_version tlsv1.2
try_private false
start_type automatic
topic +/remoteapp/# both

Inside the Mosquitto add-on configuration (previously installed, mandatory), in HA, change active from false to true:

customize:
  active: true
  folder: mosquitto

Run this command inside a linux terminal, to get the certificates needed to connect to the TVs embedded MQTT broker:

openssl s_client -host TV_IP_ADDRESS_CHANGE_IT_HERE -port 36669 -showcerts

Copy-paste inside the file /ssl/hisense.crt both certificates shown from the previous command, with this structure as an example:

-----BEGIN CERTIFICATE-----
qmierjfpaoisdjmçfaisldjcçfskdjafcaçskdjcçfmasidcf(...)
-----END CERTIFICATE-----

-----BEGIN CERTIFICATE-----
7ferusycedaystraedyasredyatrdsecdtrseydtraESYDTRASCY (...)
-----END CERTIFICATE-----

Inside the HA configuration.yaml file create these entries accordingly. Change here the smartphone mac address, previously saved by you, as stated (SMARTPHONE_MAC_ADDRESS_AUTHORIZED_PREVIOUSLY_WITH_THE_APP_REMOTENOW == AA:BB:CC:DD:EE:FF):

          {% else %}
            {{ 'mdi:television-classic-off' }}
          {% endif %}
        friendly_name: 'Hisense TV'

Inside the HA scripts.yaml file paste these scripts, useful later on to the lovelace card. Change here the smartphone mac address, previously saved by you, as stated (SMARTPHONE_MAC_ADDRESS_AUTHORIZED_PREVIOUSLY_WITH_THE_APP_REMOTENOW == AA:BB:CC:DD:EE:FF)

script.executa_hisense_input_hdmi_2:

Further debugging or exploring the MQTT broker inside the TV

You may install the software MQTT Explorer (http://mqtt-explorer.com/) and use in your local network with these configurations:

If your can not stabilish a successful connection with the TV, first, try disabling the TLS encryption on the MQTT Explorer. Some older TVs or firmwares don't have encryption enabled. If so, you may need to change the above /share/mosquitto/hisense.conffile accordingly.
