Hi Tero,
Thank you for the feedback and very extensive testing. RuuviTag is tested to be waterproof and passed IP67 testing which has 30 minutes underwater testing in room temperature. After you dried the device is it working again?
As this is a new use case, we would like to know a bit more to understand what happened here:
- How long time it was in water before it stopped working? Was it underwater all the time and was the temperature same all the time?
- There are basically three different reasons how this could have happened:
- Gore stickers is not bonded perfectly to enclosure
- O-ring has popped out from the groove when lid is closed
- In some conditions it possible that condensation generates water inside the enclosure. Usually this happens in very rare and extraordinary conditions. As we don’t know if it could be reason in this case more testing is needed.
If you can test it again we can send you transparent enclosure where we can see that Gore sticker is bonded perfectly and it easier to see if water goes in again due to cooking process. Nine hours in quite hot water is anyway quite harsh process for Gore sticker.
