What I recommend to do for preparation is:
* power all sensors
* set the sensor EEPROM to 9 bit default resolution.
Then, the readout thread is as follows:
1. trigger a 12-bit resolution conversion on each sensor for initialization.
2. write soemthing to /simultaneous/temperature to trigger all
temperature conversions at the same time.
3. wait a second
4. read /uncached/<sensorid>/latesttemp of each sensor
5. If the result for a sensor is not 85°C, store and go to 2.
6. 85°C. Check the resolution. If it is still 12 bit, that's a valid
reading. Store and go to 2.
7. Power-on-reset. Store an error. Trigger a 12-bit resolution
conversion for that sensor and go to 2.
Kind regards
