any number of consoles can receive data from a single fine offset instrument cluster. beware that not every fine offset console can speak with every fine offset instrument cluster. aside from the us/eu frequency differences, there was also a change in rf protocol in 2011, so consoles pre-2011 cannot hear sensors post-2011 and vice versa. an even less expensive approach is to use a 20$US sdr dongle to capture the data. however, with this approach you also need to build/install a pressure sensor and temperature/humidity sensor to match those of the fine offset console. this is easily done directly on a raspberry pi. it used to be even easier to do it with one-wire, but since hobby boards went out of business there aren't many places to get one-wire pressure and humidity sensors. m -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
