Owl cm180 power meter detecting

Configuration
1

Hi there

I have an Owl cm180 power meter and I’m interested in getting data from it.

I read almost everything related to 433 mhz devices but sincerely I feel lost.

after reading read this post (7$ USD 433 mhz sensor reader to MQTT) I bought an usb device, installed the addon mentioned here (Repository: Dasher; RTL433 to MQTT Bridge; Ink printer ink reporting)…
now what?
any hint is welcome, both on configuring the sensor and on how to debug the thing.

TIA

Are you able to see anything with the RTL-SDR dongle?

Although I am not attempting to interface with a CM180, I am attempting to interface with other 433 MHz devices. My first step is to install rtl_433 https://github.com/merbanan/rtl_433 and monitor the 433.920MHz frequency to see what I can read.

Are you able to read anything with the rtl_433? Also a good and fun starting tool I found was to create a VM with Skywave. The basic RTL-SDR software is pre installed and makes it pretty easy to tinker

Hi Stefano,
Were you able to read and bring data from owl sensor to ha ?
I want to do the same … i have cm160 with the tx trasmitting from a clamp my house energy. I want to track the data down to home ass so that i can check consumption from remote.

Thanks Marco

Hi Marco
Yes, I did it
If your device uses rf to communicate, you’re done
The only difficult part (for me) was related to the mqtt configuration
Once you understand how mqtt works, it’s a matter of seconds

Thanks Stefano,
What is your hw condiguration? Are you using dvb rtl-sdr usb connected to rpi2?

Is there any post I can follow to arrive to your system?

Yes, I am
I’ll post my configuration later (not at home ATM)

Hi stefano.
I’ve setup home ass on rpi2 and i have with me an rtl sdr dongle to set up.

What are the steps to install and recognize owl meter and then graph it in hass.io ?

Do you have or can you point me to a guide to do it?
Thanks a lot for the attention

Hi Marco

sorry for the delay…

unfortunately my raspi died last week and I’m still offline.
I hope I’ll get online again in the next 2 days

hallo stefano.
no problem… I’m trying to go ahead anyway…but I have a big doubt
do I have to work with Hass.io or do I need to work with hassbian?

I’ve seen that apt-get is not working and dockerfile uses apt-get inside…

thanks

Hi Marco,

I’m new in HA and moving into the depths of the “yaml” files. :wink:

My hw:
Raspberry 3
Conbee II
… that’s all !!

I’ve an Owl cm180 that I’d like to integrate into HA.
You’ve already solved this problem, could you tell me step by step, the points you followed.

I’d be able to, because I don’t even know how to make it read …

As always, thank you
