alt Hacker NewsI have about 15 Aquara sensors in my house and had no real issues for the last ~3 years. Only real annoyance with the Aquara ones is that the battery opening mechanism has the worst piece of plastic I have ever seen. I still have not found a reliably way of opening those damn things without breaking the soft plastic. If anyone has found a way to do that I am all ears
I can't open those with a coin, the plastic is too soft indeed. But if I stick them to another object using the included sticker I can just rotate the device itself to reach the battery. If you want it to be mobile you can stick it to something small or a 3d printed piece of plastic.
