Thanks for the tip, are there any ways to diagnose the power supply if I take it down & open it up?
I live in New York so for 3 months or so it does see temps below freezing, but both the Weatherflow Sky and a previous weather sensor have been up there using alkaline batteries for at least 4 winters in total. So maybe that’s the way to go, but having to take it down every 6 months could be annoying.
I was thinking about what is in the solar power accessory & the current draw of the sky and realized that I could just make my own solar power accessory (especially since it seems as though some people have already modeled out the base on thingiverse, which I was expecting to be the hardest part). I have some solar panels & a couple charge control boards laying around - could even over size the panel…
I would think that all I would need are is the control board, some pogo pins to contact the Sky, a solar panel(s), & a battery (I’d have to figure out the sizing of that too). During the summer months there is plenty of sun, so I would assume that enough power to last through the winter would be a good place to start.
Thanks again for the tip! Hopefully there is a way to diagnose the power supply (but if it’s just a small PMIC I could see that as being problematic - I had an Air go bad & took apart the old one to see what it looked like. Not a whole lot going on in that guy!)
I just don’t want to have to buy a Tempest. My current Air is fine & I like having it in a separate unit. Assuming the hubs used are the same (which might not be the case as I remember reading that all the WF1 firmware & hardware stayed static once it went into production. And with the release of the tempest it was a chance to update both for both the sensor and hub…) it may be possible to keep the Air along with the tempest, but that is a lot of money to spend.
This is especially emphasized for me as I am making my own citizen scientist-style air sensor & am including a whole host of sensors, many of which are redundant with the WF. But the way I see it is that the rain sensor & especially the anemometer would add significant cost to the sensor I am making (had considered one of those optical rain sensors, RG-9 or something is the model number, but they are something like $90 with a cheaper one being available as well, but I like to go big or go home ). Plus the whole data analysis performed by WeatherFlow is a huge plus. In particular the ‘smoothing’ & validation of data from the rain sensor (maybe this is something that is specifically needed for a haptic sensor, but I wouldn’t be surprised if an optical one has some ‘noise’ to it as well. As for a bucket style - I had one before & they can be a hassle to deal with as they collect lots of gunk over here + the accuracy has been suspect in the past. Even if I get a Davis one which I’ve looked into & would be easy to implement I still have to clean them).
From what I’ve seen ultrasonic anemometers are $$$ (I really dig the accuracy/precision, interval timing, & number of data points ultrasonic ones can provide). I believe Davis anemometers can provide a similar, perhaps greater, level of detail but that is a totally different story vs their rain gauge which is just a simple switch.
If anyone knows of any similar sensors that don’t cost over $300 I would be interested in that as well!
