Unable to get the value template correct for a tcp sensor

Hello All,

I have created a tcp server to act as a tcp sensor. The server responds with the following json string when it receives a request

{ "ch1": { "watts": "1000"},"ch2": { "watts": "2000"},"ch3": { "watts": "3000"},"total": { "watts": 6000}}

when i use the following sensor setup, the developer tools window shows a state of unknown.

    name: House Power Consumption
    host: 192.168.150.32
    port: 10000
    timeout: 5
    payload: "GET\n"
    value_template:  '{{ value.total.watts }}'
    unit_of_measurement: Watt

but, if i hard code the response (as below) into the value template, i get the expected response of 6000

    name: House Power Consumption
    host: 192.168.150.32
    port: 10000
    timeout: 5
    payload: "GET\n"
    value_template:  '{% set my_test_json = {"ch1": { "watts": "1000"},"ch2": { "watts": "2000"},"ch3": {"watts": "3000"},"total": {"watts": "6000"},}%} {{ my_test_json.total.watts }}'
    unit_of_measurement: Watt

having tried numerous combinations in the value template, (with no success), I think what the problem is, is that ‘value’ is treated as a string when it is received from the server BUT if i hard code the value, it is treated as a JSON object.
Having come to that conclusion, i tried to convert the string to a json object using either ‘value_json’ which returns blank or ‘value|to_json’ which returns the string BUT with every inverted comma being delimited with a slash e.g." becomes " .

Can anyone see what i am doing wrong?
Thanks

P.S. I have done a fair bit of searching on this topic and have found alot of solutions…but none of them are working in my case.
