this is a really simple upgrade for any Wattson or Optimmersion Wireless / Optismart Hot Water that puts generation, usage & import/export data online in real-time, viewable on any connected device on our Wattson Anywhere portal. Here is a LINK to see it in action.
The Optismart Gateway gets its data from any Wattson transmitter or the transmitter built into Optimmersion Wireless / Optismart Hot Water - it can receive data from a single transmitter so works with the 98% of Wattson installations that only need one transmitter.
It is very simple to install - it just plugs into an Ethernet port on the back of your broadband modem, so avoids all the firewall issues that made our last attempt at this so difficult to install. This is a much more user-friendly product to install and use.
