Hi

Has anyone managed to connect a Nasys water meter to loraserver.io?

We trying to connect the meter, it joins the network, but I’m not to sure about my payload decoding.

I keep getting the following on fport 99 vC1Ao5c9WIAMaFIz/Qj95maINA==, but when I look at the manual it does nit look right, but I can also be wrong, I have contacted Nasys, just waiting for a responds.

Thanks

And are you sure that vC1Ao5c9WIAMaFIz/Qj95maINA== is the decrypted payload (which you received on the ../device/.../rx topic?

Hi

Thanks, i was decoding the phypacket data and not the mqtt data.

application/4/node/xxx/rx {“applicationID”:“4”,“applicationName”:“Wi360_WUC_Test”,“deviceName”:“WaterMeter01”,“devEUI”:“xxx”,“rxInfo”:[{“mac”:“xxx”,“time”:“2018-07-08T08:49:47.558522Z”,“rssi”:-107,“loRaSNR”:2.2,“name”:“xx”,“latitude”:-24.67377,“longitude”:25.9373,“altitude”:1014}],“txInfo”:{“frequency”:868500000,“dataRate”:{“modulation”:“LORA”,“bandwidth”:125,“spreadFactor”:12},“adr”:true,“codeRate”:“4/5”},“fCnt”:1,“fPort”:99,“data”:“AGICEUwABgEQBwBiAAkBAAAAAA==”}

Thanks

Hi there

I am very new to this Lora and Lorawan but recently found out about their water meters and Im gripped, I know Lora doesn’t make the devises but the technology is used to meter etc.

My questions as a non tech guy is:

Where is the best places to purchase theses meters ?
If there is no Lora Network available where is the best place to purchase a bulk gateway.
Is there ready to use “software” and tutorials wrt say connecting 100 meters or 180 meters at once to this gateway
Is there software that can decode these meters information and put into a billing system for me to easily use
Kind regards

Garih

Hi Garth,

We got the meters directly from Nordic Automation Systems info@nasys.no, and got the AP/Gateway from https://lorixone.io, and all worked with loraserver.io no problem. Just the decoding of the meter.

Also when you get the meter, ask for a the new BLE meter so you can do firmware updates.

Hi there Q-Lion

Can you give me an indication as to what they cost in Euro.

Once again thank you very much for the service

Hi,
Would you be so kind and share code for decoding meter readings? I`m also considering buying nasys water meter reader and would really appreciate a know-how how to integrate and read it.
Tnx!

Hi, can you share link of water meter please?

Hi

I don’t do my decoding on the Lora App server itself, i do the decoding on viewing page in php.

this is what i use.

“txInfo”:{“frequency”:868500000,“dr”:5},“adr”:true,“fCnt”:1217,“fPort”:24,“data”:“sF4AALg0AAAA”}

		$data = "sF4AALg0AAAA";			
		$binary = base64_decode($data);
		$hex = bin2hex($binary);
		$chunks = str_split($hex, 2);
		$result = implode(':', $chunks);
		$msb = explode(":",$result);
		$msb = $msb[3].$msb[2].$msb[1].$msb[0]; 
		$watterUsage = hexdec($msb);

just check the page Wehrle_Modularis_module_CM3020_2.pdf
