So the purpose of this topic is just to discuss / understand possible faults with some of the original Sky units that have failed in the past. Mostly my own curiosity than any thing, so I understand if no one replies
I hate to throw things away unless absolutely necessary, and this damn Sky has me intrigued as it works some of the time, so its not entirely ready for the scrap heap, yet.
My original Sky (from the original Kickstarter) failed in various forms around Christmas and was replaced by Weatherflow. I installed the replacement and left the old one in place until it died (batteries). This weekend I finally took it down to have a play around with it.
So first thing I did was check the 8 Lithium Energisers. 4 were dead, the other 4 all at 1.42-1.48 volts. I see similar was reported on the forums before.
Not wanting to spend another small fortune on more batteries, I decided to cold-mod my original SPA which had been sitting on my windowsill in the sun since it failed last winter. Before doing so, I checked the voltage and it was around 3.4v, so had been happily charging in the warmer weather.
After reinstalling and replacing outside, the Sky was back online with all sensors working again:
Battery ticking along (the gap was the loss of signal mentioned in another thread, nothing related to this topic).
Then next day, it started to charge again in the sun, until it suddenly dropped to ~2.9v. And at that point the Sky went offline again. It woke up sometime after 6PM:
Then off again just around midnight, and back on around 6AM:
Then again around 7PM tonight, and still off now. Note the battery is around 3.55v, so thats not the cause of the unit going offline
Also note all the dips in battery. I am aware the battery reporting is low priority and can therefore cause these.
So going back to the Sky itself, the original fault was the UV and Wind sensors failing. After coming back to life, the sensors seemed to fail again:
Wind seemed to fair a little better:
The one thing I have noticed is the uptime, it simply does not stay up for more than an hour or two at the most. When the sensors originally failed it was the same, but when I put new batteries in, it was up for days at a time.
I’m more curious as to what might be causing these intermittent failures - are the sensors genuinely failing (due to age?) or could it be something else (faulty PCB eg. solder joints)?
Has anyone taken a Sky apart? If so, any photos or tips, I’m happy to take a peek inside, but if my usual dismantling is anything to go by, it will never be watertight again after I have finished with it
