Hello, we have several wireless sensors, and when checking the battery life through our MQTT micro gateway, it says each one has 99% battery, even though when manually testing the batteries, we found them to be around 80%. Is this a bug or are we misunderstanding the functionality of the battery data in the MQTT gateway menu.
We also have a vibration sensor, which we were struggling to get transmissions out of for around a month, which when we measured the batteries they were completely drained, some of which were reading negative voltages. All settings for this sensor were default, which raises concerns for battery life, as we expected it would last much longer on default settings. Is it possible they could’ve been dead from the start, or were our expectations incorrect?
It’s very difficult to read the battery percentage remaining in Lithium Ion cell batteries. If you look at their voltage output chart in the data sheet you will see it maintains voltage until a point and then drops dramatically. The alternative in our newer sensors is we report the total number of transmission the sensor has sent and we can estimate remaining battery life based on that.
As for your vibration sensor that died did you have it set to report raw or summary data? Which specific vibration sensor is it? We make a few different variants. Also what was the transmission interval set to and how often was it transmitting?
It’s currently transmitting at an interval of 30 minutes, and Im not 100% sure if it’s transmitting raw or summary data. Ive attached a screenshot of the payload.
