Hard reseting I2C bus

[varna9000]

Hi, I've got a remotely installed node with bmp280 sensor. For some reason the sensor got stuck with wrong values e.g. 170 C degrees and -133 hPa pressure. The only way to get the sensor working again is to hard power cycle it. Simply rebooting the node doesn't work. As it's already installed on a high place, it requires quite an effort.

My question/suggestion is if there is a way upon reboot of the node, the firmware to do i2c bus reset somehow so the sensor is un-stuck. I believe there are some i2c instructions for that, but I'm not sure. If there are, it would be good to be implemented in the i2c logic.

As a hardware alternative, I'm thinking of connecting a transistor to the 3.3v line of the sensor and the base of the transistor to be hooked to a GPIO which I can control form the meshtastic app (on/off)
