Hass.io Home Assistant issues

[Krotu]

I am having a few different issues trying to use this project, I am new to using github, sorry if having the issues together is incorrect usage.

I am using Hass.io Home assistant on a Raspberry Pi 3. I have a bunch of devices added to home assistant and it seems to be functioning normally.

I bought the blue dvb-t dongle pictured. Plugged into the PI, the pi can see it is plugged in but lsusb does not identify it: Bus 001 Device 004: ID 0bda:2838 (nothing displayed after this)

dmesg shows: Product: RTL2838UHIDIR Manufacturer: Realtek

I managed to install the development stuff and rtl-sdr and ran into 2 further issues: 1) rtl_test could not find a device to use 2) all the development stuff and rtl-sdr vanish after a reboot.

Is there any further instructions on how to use a RTL2838 instead of the RTL2832 when using Hass.io version of Home assistant?

Thank you.

Do you use the software defined receiver for Wireless-M-Bus with RTL-SDR

see: https://github.com/xaelsouth/rtl-wmbus https://github.com/weetmuts/wmbusmeters/issues/560

apparently the project has to run as an addon for both the hardware (usb) access and for the compiled code to persist through reboots.

I only use Homeassistant as a Docker application on my NUC, so I don't know how it works with a HAS AddOn application. But the wmbusmeter with dvb-t dongle requires a lot of resources and therefore I only use it on my own Raspberry.

see: https://github.com/zibous/ha-watermeter/blob/master/docs/wmbusmeters-with-rtl-sdr.md

There is some information on this topic at https://github.com/weetmuts/wmbusmeters/issues

I tried getting this working on a clean Raspbian Buster install but I am still hitting too many issues. I think I have the depenencies installed (the pi can see the usb dvb-t dongle now), but I can't figure out how to test rtl-wmbus or wmbusmeters.

Running app.py gives me ERROR: An unhandled exception occured: error() missing 1 required positional argument: 'msg'. Traceback: [<FrameSummary file /opt/ha-watermeter/./app.py, line 169 in <module>>] (__main__: Line 91)

Hi,

but I can't figure out how to test rtl-wmbus or wmbusmeters.

If you have the mqtt-explorer, you can check whether it works. see: https://mqtt-explorer.com/

watermeter/./app.py, line 169 in >] (main: Line 91)

This error message comes when there is an error with the MQTT Brocker. Or there is an MQTT topic, but no content - then the configuration at wmbusmeters would not be correct. missing msg is comming, when no MQTT payload is present.

It turns out that https://github.com/weetmuts/wmbusmeters has a home assistant addon. I have everything working now using that, thanks for your time though.
