How much money you can make depends on the size of your home and how well you save energy. The key to earning consistent rewards is to use connected devices, such as smart thermostats and smart plugs. OhmConnect says that customers who use a smart thermostat or two smart plugs are the ones who earn the most each month. You can make money with OhmConnect two ways. First, Texas customers who participate in energy savings events can lower their electric bill by 10-15% or more. But the savings potential is unlimited. Second, the more you reduce your usage during an OhmConnect energy savings event, the more cash rewards in your pocket.
