There are separate commands that you can use, such as /jo for just obtaining the option values, /jn for just station data. These are all documented in the OpenSprinkler API document. /ja is a collector of all the data combined.
Thanks Ray, I got it. Was I was referring to it is that sometimes the same endpoint is missing some information, while others everything is present. Is that by design? I really want to just call one single endpoint, if possible, to avoid sending many HTTP calls. Thanks.
