1) We want to actively support the geek faction in all we do where possible, even if TRV2.0 is not primarily aimed at it.

2) We will at least try not to make it unnecessarily difficult to “hack it yourself”.

Well, it’s on my list of things to fix but is distinctly non-trivial with our current ISM radios.  It maybe easier with other radios, for example, LoRa has a listen-after-TX mode as standard.  I’ll get Deniz to think about that one too, on his current researches!

Pack of heads plus a relay unit, pre-paired (optional while you're selling to techies, essential after that), and software with the features you've described.

You are absolutely preaching to the converted.  MVP, avoiding feature-itis, etc, is the ONLY way we’re going to get this done at all!
