Yes any Meteobridge model with RF (includes MBPro 2) will run independently. Reception distance is not quite the same as a VP2 console but there is the option to re-transmit from the VP2 console to the MB or include a Davis repeater.
There's no interference issues, both are simply receiving the same transmissions if connecting direct to the ISS
Thank you for your response. From this point of view, the RF reception mode seems promising. Sensors are a few dozen meters away, signal should be strong.
However, I have doubts:
1. How does PRO2 work when the Internet connection is temporarily missing ? (Can it store readings without sending them to the network for how long?)
2. What happens in case of power outages? Does the system have a backup battery? I guess in case it is turned off it is not possible to take a reading.
Since consumption is very low is there any alternative to guarantee power? A first step I would see is to connect it to a UPS, which, however, only guarantees me 1 hour. (For comparison, the old Davis console guarantees a few months of autonomy).
