RE: How many degrees Celsius of inaccuracy should a thermometer have?

I have sent an enquiry one week ago about why a digital thermometer seems to have bigger temperature difference, as comparing to the other more accurate thermometer than before.

However one of their support staffs replied as below.

“We have an overall 4 degree tolerance so that is considered accurate.”

I then replied by giving an example of forecast.

“If the forecast says the highest temperature will be 20°C tomorrow but it turns out to be 24°C, then would that be considered as accurate?”

(I did not mention anything about back yard or if the forecast must be very accurate close to where I live.)

Then the staff replied as below.

“If the temperature reading is within 4 degrees of one of our products, or a mercury thermometer, it would be considered accurate. Please keep in mind, your local forecast is not always going to be what the temperature is in your back yard. That could be taken miles from your house. For example, I live a mile away from the air port and my temperature is always about 7-10 degrees different than what they have.”

If that is the case, I am wondering if anyone would want to watch such a forecast that has 7-10 degree difference than where they live.

Please provide some opinions about how many degrees Celsius of inaccuracy should a thermometer have, and also about the example of forecast. Thank you.

P.S.:

Actually I also stated the other example of placing the thermometer in the refrigerator, but the support staff did not respond about that. I will state it below.

If I place the thermometer in the refrigerator and it measures 4°C, but it is actually 4°C less than the actual temperature, then would the foods not become rotten when
the actual temperature is 8°C?”
