Xiaomi sensor's battery consumption

[sendorm]

Hello,

I have been using the home assistant with xiaomi sensors(temperature/humidity, wireless switch, human body sensor) for a while now. The batteries on devices only last for 2-3 months. Is there a way to decrease the polling frequency to increase battery life? Or get rid of polling for switch and human body sensor all together?

Also as a suggestion: the sensors are already logging the data inside and the xiaomi home app only accesses the data when asked for the log. Other times it shows the data on screen only. Is it also possible to get the saved data only once a day, so the need to access the sensor decreases.
