Re: APCC Temperature readings
In addition to what Dale said, you might want to take a look at this post : https://ap-gto.groups.io/g/main/message/78579 and maybe to the whole thread on this subject.
Using OCH you can retrieve both atmospheric pressure and RH (which are relevant to the APPC modeling feature) from a free online service provider (OpenWeatherMap) without adding any sensor. The fetched data can then be used and mixed with your current temp sensor using the ASCOM Observing Conditions Hub (OCH). That'll work only if you have internet access from your location, obviously.
Hope this helps.
