Hello, and thank you for your feedback on the MEATER Pro. Based on your comments, it appears that you have a good understanding of how the MEATER Pro works, and are already making sure to keep the base unit as close to the probe as possible. With this not being a factor, there are a few other things that we can consider when trying to determine what’s preventing a stable pairing between the two. Assuming that the charging process is not being affected by residue on either the charging (flat) end of the probe, or the contact point on the charger, we should do a quick test to verify the range without anything else being between them. This can be done by setting the probes down, then slowly walking away from them, with both the charger and phone in hand and watching for the probes to disconnect on the app. This distance should be in the area of 30’ (10 M). If it is, we can look at other possible causes for the connection limitations, which can even be as simply as covering the probes with aluminum foil or using them in a cooking appliance with very thick walls/insulation. However, if the probes are disconnecting much closer than the expected range, or even if you would like some help with the test, please visit support.meater.com/contact-us and reach out to MEATER Support for assistance.
