Temperature correction

Hi, I’m using the temperature sensor entities in my Blink cameras rather than having separate sensors, but I’ve noticed that they’re quite inaccurate, with measured variations against an accurate temperature of -2/+3ºC. I realise I cant calibrate the sensors themselves, but is there any way to apply a correction factor? Maybe using a variable in YAML? Sorry if it’s a dumb question, but I’m very green at YAML and ESPHome and feeling my way.

Thank you, I didn’t think to search for just “compensation”. That’s solved it for me.
