Add an entry to devices.js.
Every device can be described with the following structure:
{
model: 'SDM120', // Vendor model number, look on the device for a model number
vendor: 'Eastron', // Vendor of the device (only used for documentation and startup logging)
description: Energy meter', // Description of the device, copy from vendor site. (only used for documentation and startup logging)
supports: 'voltage, current, power', // Actions this device supports (only used for documentation)
fromModbus: {}, // We will add this later
toModbus: {}, // Should be empty, unless device can be controlled (e.g. lights, switches).
},
Specify input register addresses
From the device datasheet add the addresses of the input register you want to read data from in the fromModbus key this way.
{
...,
fromModbus: {
temperature: {
address: 30001
}
}
}
Where the key temperature will be the output key to report the value.
A descriptor like this would generate the following output:
{
temperature: <value read from address>
}
