I have some ESP8266 with DHT11 modules that send Temp/Humidity to Thingspeak.
I found the MMM-REST module but there’s not too much information about it.
My problem is that I can’t find a way to get the full data on my mirror, I mean I only get the first 2 digits like 20° instead of 20.5° (excuse my english)
It’s someting about the format as I can get the full data through a browser.

 {
                    format: '%d<span class="wi wi-celsius"></span>',
                    url: 'https://api.thingspeak.com/channels/1895676/fields/1/last.txt?api_key=XXXXXXXX',
                },

So perhaps is there another way to get the same result with another module that would work with REST API ?

Thanks for your attention :)
