Hi
I’m looking to rework some code I found online so I can use it on Vera, and while I’ve managed to translate / convert a number of things, I’ve got stuck on a few things it does, around encryption/decryption etc.
All the original Lua code is here - > (https://forum.logicmachine.net/showthread.php?tid=232&pid=16580#pid16580 )
Plus there looks to be a python version too here - > (https://github.com/florianholzapfel/panasonic-viera/issues/9#issuecomment-476919658)
Here’s an extract of the code where AES 128 CBC is required?
function encrypt_soap_payload(data, key, hmac_key, iv) payload = '000000000000' n = #data payload = payload .. string.char(bit.band(bit.rshift(n, 24), 0xFF)) payload = payload .. string.char(bit.band(bit.rshift(n, 16), 0xFF)) payload = payload .. string.char(bit.band(bit.rshift(n, 8), 0xFF)) payload = payload .. string.char(bit.band(n, 0xFF)) payload = payload .. data aes_cbc, err = aes:new(key, nil, aes.cipher(128, 'cbc'), { iv = iv }, nil, 1) ciphertext = aes_cbc:encrypt(payload) sig = encdec.hmacsha256(ciphertext, hmac_key, true) encrypted_payload = encdec.base64enc(ciphertext .. sig) return encrypted_payload end function decrypt_soap_payload(data, key, hmac_key, iv) aes_cbc, err = aes:new(key, nil, aes.cipher(128, 'cbc'), { iv = iv }, nil, 0) decrypted = aes_cbc:decrypt(encdec.base64dec(data)) decrypted = string.gsub(string.sub(lmcore.strtohex(decrypted), 33), '%x%x', function(value) return string.char(tonumber(value, 16)) end) return decrypted endI can get to the point where I can create the parameters for the payload encrypt request (example below), it’s just the encryption/decryption I cant do..
data="1234" key="\\S„ßÍ}/Ìa5!" hmac_key="¹jz¹2¸F\r}òcžÎ„ 臧.ª˜¹=¤µæŸ" iv=" {¬£áæ‚2žâ3ÐÞË€ú "I’ve found this aes.lua (https://github.com/openresty/lua-resty-string/blob/master/lib/resty/aes.lua ) module online, but that requires loads of others modules too, most notably ffi.lua. Which I’d ideally like to avoid.
I also came across this aes128.lua (https://github.com/somesocks/lua-lockbox/blob/master/lockbox/cipher/aes128.lua ) but i’m not sure how that handles all the other parameters e.g specify the cbc aspect etc.
Finally there’s this aes256ecb.lua script (https://github.com/idiomic/Lua_AES/blob/master/AES.lua) , could that be converted to aes 128 cbc and then used in the above?
Any help/advice on this would be appreciated..

I just upgraded the firmware for the inverter for my solar panels and that made it possible to enable Modbus TCP.
At a glance that would be perfect for live production data fed into my home automation environment but my lack of knowledge about the protocol and how to put the data where I want it failed me.What I have:
MSR
openLuup
Vera Secure
Ezlo Plus
Mosquitto
Homebridge
Windows Server
Ubuntu Server
Quite decent PowerShell skills
Enough Lua knowledge to write my own functions and handlers
The inverters Modbus interface definitionsWhat I want to achive:
Something that can be run by systemd och anything else monitoring the status and keeping the Modbus connection alive.
Publish readings over MQTT or whatever fits my setup, the goal is to feed the data into openLuup in someway so Historian can log the data for Grafana and display current production to HomeKit (as a mqttthing light sensor, since there is no other accessory suitable at the moment).Anyone implemented Modbus TCP in similar projects or have any guidance on how to reach my goal?
Open for alternative solutions as well, all suggestions are appreciated!

Hi to all, I have a bricked vera secure that is replaced with new one. Old vera secure serial numbers are deleted from vera servers so I cannot use it. Vera secure's are orginally Sercomm's NA502 model devices. Recently I install openwrt to the old vera secure unit without problem. Is there any way to use it any automation system with internal z-wave. I install domoticz but I cannot setup internal z-wave unit, it only accept usb zwave radios. Is there any ideas?

Hello,
Looking to all the dev's and tinkerers on this community for ideas on how to implement a solution to my problem. Kind of a long intro, sorry.Problem statement:
I have a geothermal heat pump that has a loop that is slightly undersized. During the cold weather months in the Pacific Northwest (one or two months of the year), the loop can get below 32 degrees. If it goes on for a few days, it can generate significant frost heaving in my yard and under the flagstone deck, Actually fixing the issue is cost prohibitive.Current mitigation:
I have DS18B20 tied into Home Assistant and monitoring the temp of the fluid coming out of the loop and if it drops below 35 degrees, MSR triggers a Fibaro Implant to add a resister into the external temp circuit and fool the Venstar to think the outside temp is below 32 degrees and issue a Heat Pump lockout and switch to AUX heat. While this is working fine and the AUX heat is only coming on once or twice a day, I would like to simplify the setup so it runs on something other than HA and MSR. I think they are overkill for my issue. Also want this to be independent of anything else in the house so it can stay behind if I am not around to maintain.I only have two inputs and one output:
Inputs: Loop temp, Furnace running
Outputs: Switch relay to drop resistance to external thermostat connection on thermostat.
Logic is super simple:
If temp is below 36 degrees and furnace is running, turn on relay
If furnace stops, turn off relay.
I am sure even I can figure that out on Python.Trying to determine the best platform for a set it and forget it black box that works with as close to zero maintenance as possible.
Options I have thought of are:
Pi zero with a GPIO controlled relay ESPHome (Not very knowledgeable about that platform, but willing to explore) Arduino Anything anyone else suggestsAny ideas are appreciated.

Greetings,
I’m researching a migration from Vera+ to Hubitat C7 and want to know if anyone has successfully connected the Hubitat to the “HA Bridge” for local Alexia calls.
The HA Bridge does not callout Hubitat natively from what I see.Thanks for your assistance.

Hi all
Having some time off i’ve been able to invest a chunk in creating some plug-ins for Vera/OpenLuup, and will do what I can to post them in GitHub and add links on the Vera Community and here, for anyone who is interested.
But, being knew to any of this, I wanted to ask for any guidance on how and when I should share stuff ? How best do I share it ? Am I liable for anything I share? Is GitHub the best place ? What licenses should I associate with them ?
The latter is a strange one, as I don’t see how I can have any claim over the content/code itself, as I’ve learnt and leveraged so much from others..
To get the ball rolling I posted this on the ezlo/Vera site..

Hey guys,
I just registered here in the forum and honestly… I’m new to the whole topic. I‘m a web developer, so I‘ve quite a bit experience with java, js, sql and so on. But that may not help a lot in this new field.
I‘m looking forward to develop my own smart home device and I‘m looking for starting point. In General the specs are like:
The device should work with WiFi, I want to integrate it into my network I want to write an own app to control it, it may find the device in my network I want the device to be offline usable, if possible (without internet connection) I want the device to broadcast information in my network like „water is empty“, so I can use push messaging in the App it should be ready to as well work with Alexa or Apple Home Kit or Google Assistant as I Plan to develop a skill for them.Can someone provide me with some information I could start with? Like - are there microcontrollers I could go with or is it to complex and I need a raspy? Which frameworks / languages / libs could I use? I know how to do the things on the app side but not on the device side.

Vainly trying to get to the bottom of the 10 - 15 second delay for TTS with the Alexa plugin (still) anyone have a list of the possible Alexa hosts? Just wonder if the one I have (layla.amazon.co.uk) could just be slow.
Any thoughts?

Hello. First, excuse my english, please. I bought a Vera Edge looking for some way to make a digital ambient thermostat that I could manage remotely without a phone home from the device side. I am very disappointed with that device because all the "official" help of the brand goes in the way of to sign in an account and work with their cloud. I have some computer, network and linux knowledge but all my tests with the hub and a Qubino Flush 1D Relay has been unsuccessful. I connected both and I got to make some basic functions but I see myself very far to get my target. This is my last try to get something before I log in an account in getvera.com and look if I can make some progress in my project following that way.
Can somebody tell me some place where I can learn the basic concepts of this system? Guides, books, videos... Whatever it can help me in my project.
Thank you.

Node-Red on my Linux Debian box seems to be having issues now. It keeps saying repeatedly "Lost connection to server, reconnecting..." in the web browser.
I recently updated nodejs for MSR, I wonder if that might be related:
"Bump recommended nodejs version to 16.13.0; versions 14 and 15 will continue to be supported through March 31, 2022"
Nodejs version = v16.13.1
I have tried updating Node-Red that is now version v2.1.4
I also updated npm to version v8.2.0
I am not sure how or where to look at the log file for node red?
This is the contents of the nodered.service file in this directory:

Hi @ll, last days I migrated my last zwave device from Vera to zwave js in homeassistant. Out of 150 devices 1 did not go well initially but reinterviewing did it directly. Most work was to find the ex and inclusion procedure, 3 times, click, clack, whatever. I must admit that Vera is Lighting fast!!!!! With only 3 devices left, those were my under the floor switches I had to do last.
Now I am totally gone from Vera, altui, luup, etc. There's nothing more left for me on this forum. And since it was one of my "routine sites" reading I will save a few minutes a day skipping it.
I thank you all for all the kind help, warm words and laughter about the ezlo flop :-).
I hooe you all will be safe and healthy and whish you all the best!
I will stay on the homeassistant forum.
Goodbye!

Morning all. Hope all are well. Been a bit of a trying time here, but nothing we can't deal with....
.....apart from this!My coffee grinder went punk yesterday (wasn't even being used) and took out the main breakers. Once it was isolated I got everything back on line, except on TKB smart plug which was in the same double socket as the grinder.
OpenLuup claims it's failed. Z-wave server can't see it but it responds to the button pushes physically as I'd expect. (i.e. the socket turns on and off, and the LED flashes to indicate it's in inclusion / exclusion mode)
My plan is to see if I can exclude it then re-include it in z-wave server. If that doesn't work then I'll bin it, but if it does work can I then re-number it to match the original device ID and not have to trawl through my reactors? Any chance?

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)?

Hello!
I want to trigger an event (like switching on a smart Zigbee power plug) when a regular light switch (that switches regular non-smart LED light bulbs) is flipped. Is there something I can put behind a light switch to achieve this? Or something to splice in between the switch and the light bulbs? A good option would also be Hue compatible.
Thank you!
Need help backing up Raspberry Pi

Hello
I have a 64GB SD card in my Raspberry Pi.
I read some guides online and the ones that looked easy to follow use a program call Win32 Disk Imager to make an image of the entire SD card.
I shutdown the Pi and when I insert the SD card in to my Windows 10 PC, I can see drive letter D:\ appear and its label is "boot"
Looking at this disk in Windows Disk management it looks a bit strange however as it has a massive unallocated area.
Anyway I proceeded to backup the disk D:\ using Win32 Disk Imager program.
It took a long time but it has created an .img file which is 27.4GB in file size.
I then put the SD card back in to the Pi and powered it on.
Here is a "df" output from the Pi
Looks like I am not using the full 64GB of the SD card.
When I first setup the Pi I was using a much smaller SD card and then I bought a decent Sandisk 64GB card and followed some other user guide found online to clone my original smaller card to the new card and expand etc.
So have I actually just backed up the Pi's SD card and all its contents successfully ?
-
Yes, almost certainly. But when you cloned your smaller drive, you didn't expand the partition.
You should be able to extend that partition to use more space, or, format it and mount it somewhere else.
Make sense?
C
-
Hi thanks for the reply.
I think my original SD card when I first got the Pi was like 8GB max.
I'm not sure which online guide I followed now to clone the SD card and move to the new SanDisk 64GB card as it was some time ago now.
If I expand the partition now then my Win32 Disk Imager backup with be even bigger at 64GB etc.
I have seen some other user guides for backing up a Pi that didn't image the entire SD card and the resulting backup file(s) were much smaller. But those guides look more difficult / involved to follow, with many more steps etc.
So now I am unsure how much space my Pi can currently use?
-
@cw-kid a decent imager won't make your backup bigger, i.e. it won't back up the empty space. That being said, do you have some kind of limitation on your backup size? 64G is not exactly big on the current scale of things.
If run df -h it will give you human readable sizes
My reading of that is that it's currently 64G give or take, which is what you'd expect, but I'm not working at my best due to side effects
Do df -h and see what the numbers come up as.
C
-
59GB with 5.7G used ?
So why did this Win32 Disk Imager program create a 27.4GB .img file ?
If there is better imager program I should be using? I can swap to using that.
The portable disk I stored the .img backup file on, is large enough to cope with a single .img file of 64GB in size if need be.
Thanks
-
Don't forget that you're not looking at discs here. You're looking at partitions and mount points.
What I am seeing is you've got a full 64G SD allocated and mounted to various points in your file system. Most of it is in /root and most of it is unused.As to why you ended up with a 27G backup, I have no idea other than Windows is probably not terribly happy reading Linux file systems and partition info. It was never terribly well supported.
I don't really know many Windows tools these days, being a dyed in the wool BSD / Linux guy.
If you only have Windows, I used to use Acronis (many years back). The other thing you could do is use a live Linux CD and use one of the tools there. Even the terribly basic dd would be able to do it.
I would expect though that a properly functioning tool would create a 7Gish backup file. So yes, something is amiss. Can't tell if that means your backup is non-functional or not, though.
Have you got another SD card? Restore to that, shut the pi down and try and boot from the newly restored card if you need to test.

Just to toss another alternative in here, I use Clonezilla for imaging just about everything. It's not very user-friendly; you need to know a bit, like be able to correctly and surely identify which disk (/dev/sda b c d e...) is the source and which is the target, but it's a wrapper for standard tools (partclone, mostly) that do a good job of making filesystem images that back up only the used space. It also automatically grows and shrinks filesystems to new target partitions (if they fit) on restores, etc. You just make a boot CD/DVD or USB stick and off you go. It supports pretty much all filesystem types (msdos, ext2/3/4, ntfs, and of course, raw/unknown), so there's little you can't back up with it. I keep a 1TB M.2 drive in a USB 3.1 enclosure to use as a target for the images and then copy them to my NAS for long-term storage.
-
Exactly the kind of tool I'd use (although CCC on the Mac basically means you don't have to) but figured the lack of user friendliness would be a down point here
C

In Win32DiskImager there is a option for "read only allocated partitions". It is shown in the instruction linked from this thread.
The same instruction also describes how to use Gparted in Linux to resize the .img if so required. -
@archers said in Need help backing up Raspberry Pi:
"read only allocated partitions"
I did not tick that box as you can see in my screen shot above
-
@catmanv2 said in Need help backing up Raspberry Pi:
Have you got another SD card? Restore to that
No I haven't. Not the same size anyway.
I think I will buy another SanDisk 64GB SD card and make sure I can actually restore to a new card etc.

That's a sensible approach anyway.
As for the 'Read only allocated partitions' it seems that Windows struggles to see the Pi partition (other than /boot) as allocated....C

I have got a USB stick with an Ubuntu desktop Live on it. I could run that up on my laptop instead.
And then maybe use a different tool to do the job.
-
You could indeed!
C
-
I found these instructions for Linux / Ubuntu here using the dd command. Think I will give that a try.
-
Just make sure you get of and if correctC
-
If you'd run
dd
on an Ubuntu laptop for images, you might consider installing and runningpartclone
instead. It's the workhouse underlying Clonezilla, and it will produce smaller backup images (it only copies used space; dd copies, all blocks used or not).To make an image of a disk (
/dev/sda2
in this example):partclone -c -o /path/to/image-output -s /dev/sda2
And to restore that image later (same target device):
partclone -r -s /path/to/image-input -O /dev/sda2
Since the images can get very large (and may even grow larger than the filesystem allows), you can compress and split the image like this:
partclone -c -s /dev/sda2 -o - | gzip -c | | split -a 2 -b 2G - /path/to/imagefile.gz.
This will compress the output and split it into 2GB files, each having a '.gz.xx' ending, where xx is a two-letter code that keeps the parts sorted. To restore it:
cat /path/to/imagefile.gz.* | gunzip -c | partclone -r -s - -O /dev/sda2
