Lightwave Link: Settings


It is possible to find out information from the Link unit to help understand its behaviour. You can initiate a Hub call in by sending @H, to which the Link will respond:



Name Value(s) Description
trans 1-4294967295 Transaction number of the JSON packet. Increments every transaction
mac XX:XX:XX Last 6 octets of Links MAC Address
time 1420070400 Timestamp of the transaction in a local UNIX time (i.e if Link is set to UTC+2, this time will be UNIX + (3600*2)
prod wfl/lwl Denotes if the product is a WiFiLink with a Screen (wfl) or a Lightwave Link (screen-less) (lwl)
fw U2.93J Which firmware build the Link is running
uptime 12345678 The time in seconds that the Link has been running for without a power cycle, or software restart
timeZone 0 The current timezone of the Link in GMT (the Link automatically goes into DST). 0 is GMT, while 1 is GMT+1 and -5 is GMT-5
lat 51.10 Latitude of the Links location for dusk/dawn calculations
long -0.19 Longitude of the Links location for dusk/dawn calculations
tmrs 0 to 32 The number of Timers stored in the Link
evns 0 to 32 The number of Events stored in the Link
run 0 to 32 The number of Events which are in the process of running in the Link
macs 0 to 12 The number of tablets/phones/PCs the Link is paired to
ip 123.456.789.012 The local IP address the Link is using
dev 0 to 80 The number of heating and energy devices the Link is currently paired to

To find out the Dusk and Dawn time, you can send @D, to which the Link will respond:


where duskTime is the time that Dusk timers will trigger at, and dawnTime is the time where Dawn timers will trigger at.

Commands to alter Link Settings:

Command Operator Example
Set Timezone !FzP(+-)nn !FzP1 Set timezone to GMT+1
    !FzP-5 Set timezone to GMT-5
Set Location !FqP”xxx.xx,yyy.yy” !FqP”052.49,-001.91” Set location to Birmingham,UK

Altering the location will affect the time the Link has for dusk and dawn timers.


  • The Link will automatically change to DST; you do not need to account for this when setting this up. i.e. If you are in BST, when you set the timezone, you would send !FzP0 and not !FzP1.
