Table 9: Payload, clock message 

 
The clock message will be transmitted once every day and the data message at least (regulated by 
transmit interval parameter or EcoMode) once every day. The transmit interval can only be set the values 
listed in Table 10. 
 
Note that although the meter readout will occur on top-of-the-hour, the data message will not necessarily 
be transmitted at that exact time. The LoRa transmission will occur after a random delay of 0-15 minutes 
to decrease the risk of collisions. The readout for the clock message occurs at a random hour (00:00-
23:00) at a random minute in the 35-45 interval and will be transmitted immediately after the readout.  
 

 

When using message format S

cheduled

, the transmit interval cannot not be set to higher 

than 1440 minutes.

Scheduled- daily redundant

 

The data message of 

Scheduled mode-daily redundant

 contains an accumulated daily energy field, which 

is updated at 24:00 each day. In other words, depending on transmit interval settings and data rate, the 
field will be included in between 1-24 telegrams per day. This will increase the probability of the value 
being received. For example, if the transmit interval is set to “2”, the accumulated energy read at 24:00 
will be transmitted 12 times during the 24 next coming hours (every 2

nd

 hour).
