I visit this board daily. There are at least a dozen new posts a week. Maybe not new threads, but it is fairly active. The Facebook group is even more active. The subreddit is the least active.
I think what you are getting at isnt how active the community is, but how well is the company doing. Personally I think they are doing amazing. The product they are developing isn’t one that provides instant gratification, there needs to be time for learning. I’ve had various products over the years and nothing comes close to giving me a pulse of where my energy usage goes the way sense does (even if it isn’t perfect yet).
I’ve recommended sense to several friends. They looked at alternatives and most offered only the basic level of energy monitoring. Others required plugs everywhere. In the end we were unable to find a device that compares.
Sure I wish my sense detected devices more accurately and faster. Ive also been a bit frustrated at times. A reset in early June helped with most of my concerns. Heating devices now detect better and are less likely to be confused with other devices. Devices were detected much faster the second time.
Ive had sense since February and I feel that the development they have made since then is incredible and will likely only get better with time.
