Netvox R311A Door Sensor


(DCH Project) #1

Purchased and now working

Device takes 2 CR2450N batteries (not cheap)

Received APPEUI and APP KEY from Supplier (not available from the manufacturer) make sure to also ask for Netvox payload document as not on manufacturer web site (same doc for all netvox gear).

Device worked straight away

Payload:
Port 6
type : [version] [device type] [Report Type] [Netvox Payload Data ]
bytes : 1 1 1 8
value: 01 02 01 1E 00 000000000000 open
value: 01 02 01 1E 01 000000000000 closed

Type : [Netvox Payload Data] [Netvox Payload Data] [Netvox Payload Data]
[Battery Voltage :1 ] [Close/Open :1 ] [Reserverd :6 ]
1E 00 00 00 00 00 00 00
1E 01 00 00 00 00 00 00

Downlink:
Port 7
RR DD NN NN XX XX BB
01 02 00 01 01 2C 01

RR = Request Type

DD = 02 R311A device type

NN NN = 2 bytes: minimum reporting time Sec, factory default 00 01
00 01 = 1 Sec
XX XX = 2 bytes: maximum reporting time Sec, factory default ?? ??
01 2C = 300 Sec

BB = Battery voltage change report rate in 0.1V units

Still unclear how MaxTime is being used, as minTime definitely affects report rate

Still at a loss as to why there’s 2 buttons on the side of the unit, as the user manual does not differentiate between them. ??

Will update as I learn more
