-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Santa Claus brought me a new-in-the-box, really-old-model AcuRite 02064C to replace an Ambient WS2095 that has been in service at least seven years. Both are USB tethered, so I'm confident about my hardware config, although it's viability remains to be seen. (The *weectl device* utility DOES NOT support the AcuRite although there is a *weewx* driver.)
Both stations are operating. I've resisted the temptation to try to switch WeeWX to monitoring the AcuRite because there are discrepancies between the readings displayed on the indoor consoles. I don't know why I expected them to be identical, and I don't know how much precision to expect. It may well be that the discrepancies are within the limits of accuracy for this class of devices. I report to AWEKAS, CWOP, PWSWeather, WOW, and Wunderground, so I think I ought to exercise some care with my calibration in order not to contribute unnecessarily to public perceptions of Anthropogenic Global Warming (AGW). In fact I'm motivated to replace the Ambient station because the wind direction sensor failed in Aug 2023. > reading Ambient AcuRite KSBM > ---------------- ---------- ---------- --------- > outdoor temp 26.2°F 26°F 26.1°F > outdoor humidity 53% 83% 80% > pressure 29.24 inHg 29.84 inHg > barometer 29.56 inHg Right now the outdoor temp is the same on a cloudy day, but I've seen the AcuRite 2°F higher and 2°F lower. It has a small solar panel and is aspirated, so it may be more reliable. It's just merely possible that its humidity is much more nearly correct, too, because it IS CLOSE to what the Sheboygan, WI, airport is reporting. According to the WeeWX hardware pages, both stations report "pressure" so I assume that the contradiction is in the labeling on their consoles and not in what they think they are measuring. Again the AcuRite is more nearly correct, according the airport. Goodness knows how the actual altitude differs but it can't be more than a couple orders of magnitude in feet. ... so my questions are: Q1: Is this level of obsession justified? Q2: Should I attempt any calibration of the AcuRite station? Q3: Or should I just let it fly without providing any smoothing between old and new readings? Q4: Do I need to have youinses change the WeeWX map, or will my station model populate automagically? - -- .. Be Seeing You, .. Chuck Rhode, Sheboygan, WI, USA ..
