My temeprature sensor data is acting weird. When values goes thru zero, sign (positive/negative) of the value will change the opposite way, see graph:
My source data is ok, the sensor reads them from XML file. My config is like this:
- platform: scrape
resource: http://192.168.1.250/xml.xml
scan_interval: 300
name: Teplota venku
select: "temp_17"
unit_of_measurement: "°C"
