830 says "E-bike sensor battery low" when reading the Orbea Gain E-road bike's sensor.

My 2021 Orbea Gain E-road bike sensor is read OK by the 830. Everything works as it should. But whenever I start up the bike after it has been turned off I get this warning in a window bottom of screen "Ebike sensor battery low" along with a bar graph showing a few green bars. What does this mean? A speed sensor for the Mahle web motor is in the chainstay and runs off the bike's battery. When this happens the bike's battery is always well above 50%. Anybody have this show up on their 830?

    Exactly the same pattern here with a Colnago E64 and Edge 530. I've been wondering if it's the error message itself that simply doesn't read properly (i.e., translation errors). Maybe it should read something like: “E-bike battery: Low level detected”, where “low level” means that the battery is not fully charged.

    We have seen similar bogus messages with our Specialized Creo when the battery was at least half charged.

    Same problem on Giant Trance 2022 model. Have been looking for a little CR2032 battery or similar on the bike.

    I am getting the same on an 830 with a Giant Trance x EMTB and also got loads of life in the bikes battery !!

    What I have discovered is nobody at Garmin has a clue. They insist there is a speed sensor on my Orbea Gain that needs its battery changed which I know for sure, and have had it confirmed by an Orbea mechanic, that the sensor is hardwired into the bike's main battery. I have been ignoring the warning and nothing happens, even when it reads Ebike sensor battery critical (with over 50% range left on the bike's battery. Go figure.
