I already have a Raspberry and would like to turn it into an EmonBase to get the data sent by the EmonTx and a couple of probes.
What I understand is that I only need a RFM69Pi, is that correct?
However, I also understand that I can run OpenHab on the EmonBase (already installed on the EmonSD). On the screeshots, we see that from OpenHab we can control plugs and other devices. But, the RFM69Pi is a receiver only, isn’t it?
Then, to use OpenHab on an EmonBase (or even an EmonPi), we have to add a transmitter, am I correct?
Is it possible to find a board which is both receiver and transmitter?
No, the easiest way to use openhab is to installed it on the emonPi. If using the latest (18Oct18 emonSD pre-build SD card release) you will need to install openhab. See the standard RaspberryPi OpenHab install guide. If yous using an older emonSD OpenHab is pre-installed, although quite a old version. Recommend using newer version with new emonSD
