After installation Sense did a great job identifying devices in my house. It even found my TV by brand and model number. It did the same with my oven. Now after about 4 months Sense has no idea when either device is in use. They do not show up in the bubble. The oven does show on the timeline, but the total wattage does not increase when it is in use. Now it is useless to a degree. Hopefully the developers will find a fix for this issue. I have seen other post with similar or same issue.
