Garmin Tempe ANT+ connectivity problem

Just in addition: I have tried different batteries (all of them tested as more 3V)-same result, different watches (I have Forerunner 945 and Veny Sq)-same result, other sensors (bike cadence and speed, HR sensor) work very well. I just replaced battery on Garmin Tempe after weal battery signal on the watches, that's it. After that I never could connect the sensor. Thanks in advance to all for any assistance.

Make sure you placed the new battery with the correct polarity (i.e. not upside down). Try removing the battery, waiting 60 seconds, and placing the battery back in. Some ANT+ sensors exhibit unpredictable behavior when the battery is removed for a shorted time. Waiting 60 ensures the tempe is completely powered off.

I have tried 3 batteries, all new and I have tested the voltage of each. Polarity is also correct, it is quite hard to mix it :)  Tried to wait some time, also tried to adjust connection right after (3-4 seconds) battery insertion. Well, will try to remove it and wait 60 sec, but I always do not place it in very quickly. I replace batteries on all other sensors I have without any further connectivity problems, only Temp ANT+ has this issue.

I have exactly the same problem as you described it. Still no solution found? I also tried different new batteries, but it's not working anymore...

No solution and nothing helped, I decided not to waste my time, attempting to fix it. I just stopped using the sensor, support team advised me to buy a new one :) Very smart recommendation, but it worth my time :) Will buy a new one once

Thanks for you answer. I'm not going to waste any more time on it too. What a great solution you got from the support... :-)

How do I even know if the Tempe was connected

You don't.

Have exactly the same problem. Replaced the battery 3 times now. Each time the tempe only works for roughly one day and then nothing. Contacted garmin and they are sending me a free replacement since it's still under warranty.
