Hi
In my ongoing quest to try and retrieve as much information as I can about the amount of energy I’m using , I found out that I could use SNMP to see how much power (watts) my UPS is handling .
To do this, I installed snmpd/snmp on my Vera linked Raspberry Pi, and then ran the following command.
local command = io.popen("ssh -i /etc/dropbear/dropbear_rsa_host_key pi@192.168.102.37 'snmpwalk -Os -c public -v 1 10.10.10.103' 2>&1") local response = command:read("*a") print(response)Which returned a huge amount of information, which prompted me to ask the community here if there anything on Vera/OpenLuup that people have that can process this sort of information into a new devices and associated variables to then monitor/track going forward ?

Hi all
I’ve been on a mission for a while now to try and track down where all the energy we use is going (so I can explain the exorbitantly high electricity bill !) .
I’ve done a few posts on this subject already, see below..
https://smarthome.community/topic/534/unifi-energy-report-how-can-i-retrieve-the-value-via-http/6 https://smarthome.community/topic/584/luup-hue-energy-watts-calculator/17?_=1623603224863Plus I’ve got various energy meter plugs around the house to help me too, but when compared to my CurrentCost (whole house) energy meter, I’m still unable to account for 200+ watts when i believe everything of note are switch off (so no dishwasher, no washing machine running etc.)
Tracked items so far include.. Media Centre (TV/NAS etc.), Office Desk (Laptop/PC/Monitor etc.), Hue Lights, Fridge…
What items/devices could I be missing ? What else could i create a pseudo energy (watts) calculations for ?For example (2), I‘ve got a couple of Sonos Music players, which are always on, so I’m thinking as they are a media device that report their status, i can calculate a pause/stop watts rating vs a play rating..
Any thoughts on what the missing power hungry items are in a normal house, and/or any new pseudo watt calculator ideas?

Hi all
I’ve recently started to build out my own ‘Homer’ dashboard (https://github.com/bastienwirtz/homer) and I must admit I really like what it’s given me.
Thinking about future use-cases. I can see potential for this being an alternative (albeit simple ) UI for Vera/OpenLuup..
Is anyone else using Homer ?

Morning, gurus. Hope all is well.
Recently some of my voice activated actions have felt very laggy. Digging into it reveals that it's not the action that's slow, but the response from Alexa, To test I ran a simple speak from Reactor by pressing the 'play' button and there's a 10+ second lag between the command being queued and the voice confirmation in Alexa.
While this is not critical in terms of operation it is making some of my activities with multiple voice feedbacks take enough time to think stuff is broken 🙂
Quick log snippet (which I hope is enough shows the lag:

I am a pretty active forum user over on the QNAP forum and there has been a number of viral threads there and on reddit about the spread of ransomware on these NAS.
I wanted to post here to say that this is a fresh reminder to be very cautious with the current state of the affair when it comes to smarthomes and the trend towards IOT we are observing from all these companies attempting to make our homes cloud dependent, opening so called "secure tunnels" to their servers which can turn into very real exposures to your LAN (home network).
In order to mitigate it, QNAP released a firmware which now has autoupdate enabled by default (reminds me one other company...) and IMHO is the climax of absurdity but in fact when I come to think about it is how the amazon echos and ecobees work for example without even offering the ability to disable.
I am in no way a security expert but have had enough exposure and interest about it to recommend using a real firewall for your home network to block these backdoors if you have a smarthome and avoid these cloud oriented platforms and devices as if they were COVID.

Hi,
I have a piece of code that returns the Watts used by all the PoE devices on my home network. I’m trying to set it up on Vera so that can retrieve that value in a similar way I would retrieve a Vera variable via a http request.

Has anyone successfully incorporated incoming call(er) information** within an automation workflow?
I'm talking about having Alexa speak out the name and/or phone number of a caller, or activating a routine/scene based on that info.
Always been a dream of mine. Wouldn't know how to achieve it! Do they make an Ethernet/WiFi-connected CallerID box?
**from a LANDLINE, not a MOBILE PHONE (although in the case of my Google Voice #, both lines ring, and if my smartphone is home and turned on, I could see invoking Tasker somehow)

Some of you may know that I took at shot at building an alternate geofencing solution for Vera. The core of it was system agnostic, using the OwnTracks application and AWS lambdas to track devices and keep a central data, then disseminate that to the Vera via a websocket-based plugin. It worked with other apps as well, including Tasker and GPSLogger, but of the dozen people that were testing it, most used OwnTracks.
A lot was learned in the process, not the least of which is that the success of any such solution is highly dependent on the phone and its settings. Phone manufacturers love to set things up for the longest battery life, of course, but that's usually very anti-geofencing behavior. In the case of at least one brand, it was unusable and the settings could not be modified. It was also cost-prohibitive to maintain on Amazon, as AWS grabs a dime here and a dollar there and before you know it, it added $100/month to my AWS bill, which my wife deducted from my Scotch budget. Unacceptable.
But it's quite reasonable to use OwnTracks to a local endpoint, and I could pretty easily replicate the functionality as a local application, or maybe even as an additional endpoint built into MSR's API (still separate port and process, but in the package).
So the question really is... would you do it, or would you be too concerned about the security risks associated (e.g., dynamic DNS and NAT mapping in the firewall necessary for the phone to contact the service when not on LAN)?

After having optimized my video processing integration of 8 cameras into my openLuup based automation, I have been wondering what I could possibly improve on my setup. Instead of pestering @akbooer with petty localized console optimizations I am looking at these Apple Homepod minis as a potential improvement from my alexa based voice command system. openLuup is presently already bridged to both platforms using habridge and homekitbridge.
I am seeing two issues with Alexa:
Speed. The cloud processing of the voice commands takes ~1s (I don't use anything cloud to cloud) and I would really prefer it to be local. These devices can go a bit crazy when they lose DNS connections and sometimes do random things. Privacy because all the recordings go to the amazon cloud all the time.I have been exploring open source solutions for this but I would lose the benefit of optionally being able to go to the cloud for search information.
The downside of the homepods are that siri is not nearly as good in terms of helpfulness as alexa at this point. They also don't have a version with a screen which I found to be very useful at a couple of locations on the other hand, the sound quality of the homepod minis seem to be better than the echos...
What do you guys think?

Reposting an article I got from a reddit thread.
I won't stop advocating against cloud dependence and unnecessary cloud reliance especially in the field of smarthomes.
I divested from a fairly large ubiquiti unifi system almost a year ago and I never connected my controller to their cloud service but as some may have sensed, it was a direction they were going towards. What got me off of it actually was the large disparity in product performance and a decreasing trust in the company with large amount of dubious advertising, inconsistent products for some of which the hardware could obviously not meet the marketing promises. -

Not having a background in IT, I only stumbled into linux because of home automation.
I got familiar with OpenWRT because of vera and ubuntu server because it is the newbie friendly, seemingly most supported distro.I am looking for a super lightweight linux distro to act mostly as a server (potentially to host the whole home automation controller pyramid) either for a laptop or a mini PC. I just gave peppermint a shot and was surprised to see a CPU 6C temperature drop at idle vs. ubuntu server in spite of it having an additional GUI. Being a laptop, the GUI is convenient.
I am now thinking of Elive (Debian based) and WattOS (Ubuntu based).
Any recommendations? -
For our workloads (web and apps, mainly in cloud), in combination with Kubernets, we regularly use Alpine. it's very lightweight, but you can build an image with exactly the things you need: https://alpinelinux.org/

Hi Raf, i know Debian because it runs on a Pi and the headless version looks pretty small and quick.

Debian all the time, anywhere!

At PointPub, we use Debian anywhere, either on rPI, pine64, rockpro, servers, VMs, etc.

Thanks, I definitely looked at both Debian and Alpine.
On Debian, it seems like you all like the hardcore base OS. Any reason not to consider the seemingly lighter offshoots like Elive?
I am struggling a bit to already see big differences between debian and ubuntu which is based on it but then they each have other distros spawn off of them too... They share the same linux kernels, following different version update strategies. Maybe I am wrong but shouldn't programs and packages compiled on one be able to run on the other?
For having dug deep into openWRT for example, the shift after chaos calmer to the LEDE branch led to binaries no longer being compatible due to a change in the C library used in the kernel. I don't seem to see anything similar between ubuntu and debian. Merely different apt repository differences?
@DesT, what is preventing you for example from running the ubuntu build of z-way-server on your debian install? -
@rafale77 I can try and let you know! Should work!
-
@rafale77 The binary is working, I can start it. I would need to do a test to "upgrade" my real setup!

@rafale77 Looks like I can be able to do something, I just need to find which file I need to check to make sure I don't override something!

They might, and probably will. But sometimes they wont't. I can't honestly recall the lat time I found that happening, and I can't also recall the last time I tried to do something on Ubuntu that wouldn't work on Debian (or any of the derivatives) that didn't
Most of the issues that I used to struggle with were installation methodologies and locations.

The files in the folders /opt/z-way-server/config and in /opt/z-way-server/automation/storage are the ones related to your backups in the expertUI and smarthomeUI respectively.
The plugin files typically don't get overridden but just in case, they are stored in /opt/z-way-server/automation/userModules. -
Thanks! I think I will test Elive next! Then maybe Arch(Bang?) or Bohdi.

It's more lightweight and so far I am liking it. The use of the laptop for the home automation controller has the advantage of including a built in UPS... and a screen and keyboard when needed.

True! but it also depends on how old the CPU is and what you buy. The Chromebook class of Gemini Lake CPUs have TDP of 8W! From my testing they consume about the same power as a rPi 4 (with the screen off) at peak and run much cooler while offering 3-4X the performance. Yeah they are more expensive but not by much. My N4100 mini PC is one such example... passively cooled and powered by POE. power requirements are even lower than for an rPi4.
I am testing a refurb laptop with an i7 8550u 15W-TDP which is now completely passively cooled idling at 34C (ambient of 22C) and needs to be "benchmark stressed" to hit 65C. (ok I admit it, I modded the cooler to get to this result. The laptop offers more room for passive cooling solutions...) Surprisingly as I reported above the peppermint OS made a difference vs. ubuntu which led to my question.
I left the laptop on with the lid closed overnight and to the touch, I can't tell that it is on... No warm spot anywhere. With ubuntu server it would slowly creep up and steady at 42-43C which was detectable to the hand.

Hehehe. Chromebooks are a bit different I accept. And not what I was thinking about running laptops. Some laptops are fine running with the lid shut. Others not so much
