I am sure that RED Wifi Meters will revolutionize the entire industry, what they bring on the table is awesome and I don't think that there is another competitor who is doing this right now
Probably there is not, but be sure if they succeed with this, there will others who will try to copy this and also trying to sell it into the market
It won't be so easy to copy what they're doing because they spend a lot amount of time trying to build this and running test with it. Perhaps the next competitor who will try to do this will be after 2 or maybe 3 years later
