I want to set up an input slider who’s value is used in an MQTT message. Slider will have 0-255 positions And this need to control the last 2 characters of the payload Payload needs to be 000000XX where XX is a value from 00 - FF taken from the slider. I can set up the slider and can send the mq…

Does this help: [image] Changing a decimal value into a hex value (jinja) Configuration When you’re experimenting on this, remember that you can use the template dev tool to test your formatting. {% set value = "VAL RETURNED BY SENSOR" %} {{ "%+0x" | format( value | int …

Thanks for the info. Tried using the template tool but can’t create a valid script. Can anyone offer more detail.

You dont put scripts in the template tool. It’s for evaluating templates only. If you put this in the template editor what do you get as the result: {% set value = states.input_number.your_input_number.state | int %} {{ "%+0x" | format( value | int }}

Think you are missing a ) after int in 5he second line. This give me the hex for the slider value with a leading + (ie +FF) How can I amend this to give 6 leading 0s insted of + (ie 000000FF) This could then be used to pass to the mqtt message.

Oops, yes sorry about the missing bracket. There’s probably an easier way to do it but this should format it how you want {% set value = states.input_number.your_input_number.state | int %} {{ "%+0x" | format( value ) | int }} {{ value | replace("+", "000000") }}

[image] anon11644107: {% set value = states.input_number.your_input_number.state | int %} {{ "%+0x" | format( value ) | int }} {{ value | replace("+", "000000") }} ) is still in the wrong place need to be after the int or the result is 0 {% set value = states.input_number.your_input_number…

Hopefully this should work: payload template: "000000{{ "%0x" | format( states.input_number.your_input_number.state | int ) | string }}"

Using this give me an error when checking the config file. Configuration invalid CHECK CONFIG Error loading /config/configuration.yaml: while scanning for the next token found character ‘%’ that cannot start any token in “/config/automations.yaml”, line 1173, column 36 Sorry for all the questions…

payload template Should be payload_template

I did spot that one. Tried both ways but configuration check still give the same error.
