You need to open the case of the Radbot to get access to the pins on the PCB and then connect a serial port to them. The easiest way to do that is by connecting a serial-to-USB adapter like this one: <a href="https://thepihut.com/products/usb-to-ttl-serial-cable">https://thepihut.com/products/usb-to-ttl-serial-cable</a>. You can then use the CLI via any terminal emulator connected to the virtual COM port that the adapter creates.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I had to open my Radbot all the way to expose the PCB, but you could conceivably use long bogo pins through the battery hatch, but I think that would take you longer than opening the case.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I’m not sure what you’re using (or planning to use) to monitor the signal, but whatever you use, it needs to now the key of the Radbot to decrypt its messages. (Thus you need to set a key that is known to you via the serial port.) In my case, I had an old RTL-SDR dongle lying around which I could use to confirm that there is regular activity on and around 868 MHz to confirm that the Radbot is alive before getting into it. It took a bit of coding effort, but I can now receive the messages on a raspberry pi with a cheapo 868Mhz transceiver and it works fairly reliably. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Cheers,<o:p></o:p></p><p class=MsoNormal>Christoph<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b>From:</b> OpenTRV-dev <opentrv-dev-bounces@lists.opentrv.org.uk> <b>On Behalf Of </b>Damon Hart-Davis<br><b>Sent:</b> Saturday, 14 November, 2020 18:58<br><b>To:</b> Gary Gladman <gary.gladman@talktalk.net><br><b>Cc:</b> Closed list for developer discussions <opentrv-dev@lists.opentrv.org.uk><br><b>Subject:</b> Re: [OpenTRV-dev] Dongle<o:p></o:p></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Hi,<o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>The only Radbot that currently exists as stock is Radbot 2.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>If you want to do the comms you’d need to associate the ID (at the hub/controller) and have the same key set for all the devices to be listened to and in the things listening:<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal> <a href="https://github.com/opentrv/OTWiki/wiki/Command-Line-Interface">https://github.com/opentrv/OTWiki/wiki/Command-Line-Interface</a><o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>In practice that means that you’d need to create a secret key, put it in the Radbot(s), and in the hub/controller, and associate the Radbot IDs at the hub/controller.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>The left-most pad is +ve (next to the +ve battery spring) and the right-most is -ve (0V/GND).
