Page 13: Downlink
CMi4170 User’s Manual English 6.3.1 Downlink CMi4170 supports configuration via downlink, i.e. sending commands to an end-device via the LoRaWAN network. Note that this feature should only be used sparingly due to bandwidth consideration. Communication via downlink can only be made in a short window after an uplink transmission from module to server. -
Page 14: Adaptive Data Rate (Adr)
Table 4: Downlink commands Adaptive data rate (ADR) CMi4170 uses Adaptive Data Rate (ADR), part of the LoRaWAN standard, where the network server determines the optimal rate of communication for the module based on current signal conditions. In best case, the module will use its highest data rate (DR5) in order to be as energy efficient as possible. When signal conditions are poor, the network server will incrementally lower the data rate until it is able to receive the message. -
Page 15: Message Formats
Table 6: EcoMode transmit interval settings, EcoMode (10 years) Message formats CMi4170 has several different message formats. Each one will be described in detail in this section. 6.6.1 Message structure Message formats Standard, Compact, Scheduled – Daily redundant, Scheduled Extended, Combined heat/cooling and Engelmann are encoded in M-Bus format (M-Bus standard EN 13757-3:2013). -

- Page 18 CMi4170 User’s Manual English 6.6.2.4 Scheduled mode For message formats of type “Scheduled” (Scheduled – Daily redundant and Scheduled – Extended), two types of messages will be transmitted from the module - a clock message and a data message. The difference between the two is described in Table 11.
- Page 19 CMi4170 User’s Manual English 6.6.2.4 Daily redundant The data message of Scheduled mode-daily redundant contains an accumulated daily energy field, which is updated at 24:00 each day. Depending on transmit interval settings and data rate, the field will be included in between 1-24 data messages per day. This will increase the probability of the value being received.
