OpenTRV does not use WiFi at all, and does not depend on its radio (or the Internet) for its correct operation.

We haven’t written the back-channel yet but it’s on our list to do Real Soon Now.  You could even help us get it done.

Open source hardware and software so you can’t be locked in, see our repos:


We will keep some specific stuff under our hat done for specific clients or that we need to to protect some business revenue, but the plan is always to have as much as possible open.

A Web shop will be appearing soon, maybe this week.  Keep watching this list and opentrv.org.
