Kinkeni Zigbee Smart WiFi Temperature Sensor install not complete

Continuing the discussion from Freezer Monitor using:

Kinkeni Easy Operation Zigbee Temperature Sensor Controller

Zigbee Model – TS000F, Zigbee Manufacturer - _TZ3218_7fiyo3kv
Manufacturer – Mumubiz, Model - TYZGTH1CH-D1RF

I got one of these and it installed easily but I have one problem. I am unable to have the relay turn on via “Auto settings” in Zigbee2MQTT, Devices, Exposes.
I found in the state.json file Under config/zigbe2mqtt there is this block:
‘’’
{
“auto_settings”: {
“enabled”: “on”,
“temp_greater_then”: “off”,
“temp_greater_value”: 2.8,
“temp_lower_value”: 1.7
},
‘’’
it seems that there should be another line:
‘’’
“temp_lower_then”: “on”,
‘’’
between the two “_value” statments.

In Zigbee2MQTT, Devices, Exposes. “Temp lower than” is blank, when I set it to on and click the “Apply” button, using MQTT Explorer,I can see that code similar to the code in the state.json including the missing line (“temp_lower_then”: “on”,) is sent to the sensor. The sensor then responds back with the same but missing (“temp_lower_then”: “on”,) After refreshing the screen it reverts to what it was “Temp lower then” is blank.
Can anyone tell me if this is a problem with the sensor or some file buried somewhere in Home Assistant and how I might fix it?
