[OpenTRV-dev] Dongle

[Damon Hart-Davis]

Hi,

Radbot 2 is the thing that is in stock and you can buy now from Amazon or direct from radbot.com.

The serial port is on those pads above the battery contacts.  We haven’t published a dongle 3D design but it’s nothing magic.  If all you needed to do was to talk to the CLI to load in a new key then you would only need 4 contacts (0, Vcc, TX, RX) long enough to do that, so something bodged should do.

Look on github.com/opentrv for the hub and boiler controller designs, which are fully published (h/w and s/w), eg I’m using a REV10 for boiler control:

    https://github.com/opentrv/OpenTRV-Arduino-V0p2/tree/master/Arduino/hardware/REV10

and a REV2 for my stats hub (being listened to by the also-published Java running on a RPi):

    https://github.com/opentrv/OpenTRV-Arduino-V0p2/tree/master/Arduino/hardware/REV2

We’ll probably still get to ARM, as part of const-reduction work.  I think I can categorically state that it won’t be an M1!

The radio will be useful for some commercial applications but not for many domestic uses.  So we have a choice whether we build and support 1 or 2 SKUs (product lines) for example.

At the moment most of our energies are going into getting sales, eg as part of GHG and ECO3.  If Vestemi is successful and generating revenues then potentially more TLC can be spent on OpenTRV.  Nothing stops others contributing to OpenTRV regardless.
