TIDE = Speed (re: Modbus)

Case in question: our own in-house test of an energy meter with RS485 interface running MODBUS protocol.

One of our potential Customers wanted to us to create a small Tibbo BASIC app that would query the meter and show the data on a simple HTML page. Two hours later (spent mostly on connecting and arranging things) we had a working application prototype. The source code is published here.

We didn’t go as far as to format the data (in KWatts, etc.). This demo displays raw contents of MODBUS registers.

Now that we’ve got Wi-Fi working (and ZigBee coming) it is possible to use our modules in power metering applications — a huge market worth gazillions*.
