We are working on this one. We know that some people want to share their sensitive data with us. 
This is going to be part of Turris OS 5.1 release. Will be announced and there is going to be a blog post about it.
In older version of Turris OS 3.x, there was uCollect since beginning for our routers and it was aimed for the devices which were given to the people during our security research. If I remember correctly, we are talking about 5 years ago or something like that. That’s why we do a “major refactor”. I mean prepare from scratch something called Sentinel, whould would be scalable and make everything quicker and simple. Our devs are doing what they can.
Ehm, you found something as feature flag. In Turris OS 5.0, it does nothing. In Turris OS 5.1, it does miracle, no I am just joking. That’s prepared Foris backend and there is also package for reForis frontend, but as I said, it’s feature flag. Let’s wait for 5.1.
Are you sure that it does not run? Isn’t there something in messages?
