Multical21 always broadcasts the meter values regularly. Yep, that is one radio signal every 15 seconds, for 10-16 years, depending on the model. Pretty remarkable tech.

 

A passive listener will of course not drain its battery more.

I see you've started on energy meters as well, I was wondering if you think we should be able to pick up data from our Aidon energy meter as well? As far as I can tell they do have wireless enabled, but I'm uncertain about whether they publish MBUS notification packets. I've contacted my power supplier about this. If it should be possible, is there anything I can do to help getting it implemented?

[wmbusmeters]

Sure, adding more meter is always fun!

 

However a quick google on Aidon energy meters seems to indicate that they use a proprietary protocol to build a mesh network to reach the municipality. Even though they seem to use the same radio freq band as wmbus, it might not be wmbus.

 

But I could be wrong. So please check.

 

[Tor Magnus]

I contacted the power company, but so far no response. ?

@wmbusmeters - got the im871a USB stick today, and installed your program on my Pi, but I get "No wmbus device found!". It seems to be recognized, I see the im871-device in /dev. Any suggestions?

[wmbusmeters]

Have you tried both auto and /dev/ttyUSB0 (or whatever tty it was assigned) ?

Auto only works if you have added the udev rules.

And did you check the read/write permissions on the ttyUSB0 device?

I've tried both auto (have added udev rules) as well as /dev/ttyUSB0 (and USB1). rw set to 777 right now, still same error. 

 

@Tor Magnus. have you got yours to work?

Run

wmbusmeters  - - c1 - - debug /dev/ttyUSB0

 

and email me the log output. My email is on the github page.

 

Please try from a linux computer as well. (I mean the build computer... ? )

It arrived yesterday, but I didn't have time to pick it up. Will be picking it up today so I'll be able to test it later.

Got this:

 

(cmdline) using usb device: /dev/ttyUSB1
(cmdline) number of meters: 0
(serial) opened /dev/ttyUSB1
(serial /dev/ttyUSB1) received "00"
(amb8465) are you there?
(serial /dev/ttyUSB1) sent "FF0B00F4"
(serial) closed /dev/ttyUSB1
(serial) closed /dev/ttyUSB1

(serial /dev/ttyUSB1) sent "A5010100"

No wmbus device found!

Anyway, as this is a very old Pi I've gone out and invested in a new 3B+ which I will try as soon as I get back home. Great excuse to get a new Pi.

Looks good!

 

Would have been cool if this was implemented as a HA plugin, but I guess I can MQTT it.

[Tor Magnus]

Hm, flow_temperature does not seem to get updated, even after 8 packets.

Interesting, it could be that you have a meter with another configuration. The customer (municipality) can pick and choose what values the meter should send, depending on what they are interested in.

 

Run with --debug for a while and look for long and short packages. In the long ones, you should be able to see almost exactly the contents of the package received.

 

If you find something that you would like to have in the json, it is easy to add it.

Very strange, my new 3B+ has the same problem:

Looks like it's not sending it. There's no extra information as far as I can se.

[Tor Magnus]

Would it be possible to be able to define a template json format to use with mqtt?

 

Would be awesome if one even could include sending an initial discover message for home assistant as well, as described here: https://www.home-assistant.io/docs/mqtt/discovery/

I seem to be getting flow temperature, @Tor Magnus:

That's odd. Could my meter be a bit borked?

Are you also in Skedsmo (so same meter and config)?

Yay!  MQTT published and grabbed into Homeseer:

Do you want a different json format than the one that wmbusmeter currently generates?

Try placing the dongle in different angles, sometimes it receives better in a different orientation.

Or try closer to the water meter.

Yes, that would be the idea. Also with Home Assistant and auto-discovery of devices it is possible to initially send a config for the sensor. I'm currently containerising wmbusmeters, and I'll see if I can get the container to send a config message on startup before staring wmbusmeters.

I'll have a go using a USB extension cord. A bit limited when it comes to moving the NUC that it's attached to.

Jeg fikk installert en vannmåler i går, ifølge rørleggeren så var muligheten for å lese av vann automatisk i måleren men at det ikke var aktivert av kommunen ennå.

Løsningen på sikt skal være at søppelbilen har en mottaker og at vannmåleren leses av når søppelbilen tømmer søppel. Levetiden er på 15år på vannmåleren.

Pinne i posten på vei til meg også, vannmåler ble installert i våres.

Hvilken endte du opp med å bestille? Bor også i Skedsmo, så tenker et nytt prosjekt denne våren.
