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 am user of vera controller. I have a dahua door intercom with relay. Relay activates with username and password authentication.

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)?
Using luup.call_delay() in the browser code test boxes
-
Why doesn't luup.call_delay work in the browser test boxes for Vera & openLuup?
eg this doesn't work:
local m_TestCount = 0 -- Must be global: it is a delay timeout target function delayTest() print('m_TestCount = '..m_TestCount) m_TestCount = m_TestCount+1 if (m_TestCount > 10) then return end print(pretty(delayTest)) print(pretty(_G.delayTest)) local m_PollInterval = 1 -- seconds local result = luup.call_delay('delayTest', m_PollInterval) print(pretty(result)) end delayTest() return true
-
Ah yes.
Well, it may, in fact, be running...
Since the routine which runs the code has exited before the delayed callback is run, there’s no way that its output can appear on the screen.
If you did an action which did not require output (eg. set a device variable) then you might find that it works.
-
...it’s also possible that it’s sandboxed such that the system can’t find the named global callback function.
I did test this once, but have forgotten the details of how Vera behaved!
-
@akbooer said in Using luup.call_delay() in the browser code test boxes:
but have forgotten the details of how Vera behaved!
Just to remind you; badly.
OK not surprised I'm going around in circles - I should know better by now. I modified the example code to write to the log, instead of the UI. In Vera, in either Vera's UI or AltUI the log shows:
LuaInterface::CallFunction_Timer-5 function delayTest failed [string "local altui_device = 5..."]:10: bad argument #1 to 'insert' (table expected, got string)
Using AltUI with openLuup, I get similar, where 0x27151d0 is the called function (as printed by the test code):
luup.delay_callback:: function: 0x27151d0 ERROR: [string "RunLua"]:10: bad argument #1 to 'insert' (table expected, got string)
OK so then I test it in one of openLuup's three console test windows (I came across these just recently) and as expected with your code; it all works! I think I figured it had all failed because I never saw the test code printed in the log. Your console test windows just show this, rather than listing the code:
openLuup.server:: POST /data_request?id=XMLHttpRequest&action=submit_lua&codename=LuaTestCode2 HTTP/1.1 tcp{client}: 0x33b3328
So it can be made to work - looks like altUI and Vera UI need to pass the function reference, not the function name string? Or whatever is needed.
Out of interest I have noted that luup.call_delay can use sub one second delays in openLuup as previously mentioned on the Vera forum. I'm unsure if Vera can or can't.
I did some tests and found on a rasPi that occasionally, a one second delay could be well over one second on occasions (have seen two seconds). There could be any number of reasons for this - just measuring the time alone affects the timing (I used socket.gettime()). Plus with different things happening at the same time, it can get weird. But I do have a plugin that runs code every minute and receives/handles a lot of bytes, one by on, via the infamous Vera "'incoming" feature. I should probably rewrite that plugin code one day, if I can rember how it all worked.
There may even be an argument to code a finite reduction in all delays by some fudge factor representing the delay processing time eg say 20 milliseconds but that's getting too pedantic.
-
Ah yes, once again.
The Lua Test windows in openLuup (I never found just the one to be sufficient) are implemented quite separately from AltUI, and you don’t see the code because it is sent as a POST, not a GET.
Incidentally, you do recall that
pretty()
is available to you in all Lua Test windows to examine tables? As in:print(pretty(luup.devices[2]))
It works in AltUI too (it’s the same code.)
-
For those interested, I modified the code above to show the differences between the one second delay requested and the delay that actually occurs. This code only works in the openLuup console test windows as noted above. "Max delta" is the figure of interest. It captures the highest mismatch between the requested delay and the actual delay over a two minute testing period 120 tests. I experience fairly long mismatches from time to time. Would be interested if others could run the code and see if they have the same experience.
local socket = require('socket') local m_pollTime = 1 -- seconds local m_loopCount = 120 -- two minutes of testing local m_testCount = 0 local m_runTime = 0 local m_deltaTime = 0 local m_maxTime = 0 local m_startTime = socket.gettime()*1000 local m_lastNow = m_startTime - (m_pollTime*1000) -- must be global: function is a delay timeout target function delayTest() local now = socket.gettime()*1000 m_runTime = now - m_startTime m_deltaTime = now - m_lastNow - (m_pollTime*1000) m_lastNow = now if (m_deltaTime > m_maxTime) then m_maxTime = m_deltaTime end luup.log(string.format("HELLO TESTING: m_testCount: %i, time: %.0f, delta: %.0f, max delta: %.0f", m_testCount, m_runTime, m_deltaTime, m_maxTime), 50) m_testCount = m_testCount+1 if (m_testCount > m_loopCount) then return end luup.call_delay('delayTest', m_pollTime) end print('Starting test') print(delayTest) delayTest() print('Finishing test') return true
-
@akbooer said in Using luup.call_delay() in the browser code test boxes:
it is sent as a POST, not a GET
I've run code consisting of over a thousand lines regularly in the Vera UI and AltUI test windows and they generally work OK. But using a GET and sticking all that stuff effectively into a URL is a bit scary.
I have found that the Vera UI test window will occasionally fail - seems to occur when the code contains arrays declared with heaps of stuff in them like look up tables for example. I have never bothered to chase it down. I just switch to AltUI on openluup.
I presume that we could ask amg0 to modify his code to use a POST for the test window in AltUI, when working with openLuup?
An yes I use pretty() - very handy.
-
This variation in delays is to be expected, since the system IS doing other things. The biggest culprit here is AltUI, since its inevitable outstanding lazy-poll request will get answered when variables are changed. It would be very interesting to rerun this without AltUI running in a browser window (although maybe you did that?)
Secondly, there’s absolutely no excuse to need to load that code over HTTP. There’s no way in code development that you’re actually making changes across that whole codebase. Simply move the static parts to a file and use require() in the part that you are changing in the interactive window. (Be aware, though, that if you do change the require file contents, it will not be reloaded unless you explicitly clear it from the packages cache.)
-
@akbooer said in Using luup.call_delay() in the browser code test boxes:

Yep - appreciate that. I did a few tests and found a plugin that was being accessed very regularly and was doing this in a for loop of varying loop count/length - and then the json then being processed by openLuup:
lul_json = lul_json .. '{"Id":'..v.Id..',"LastRec":'..v.LastRec..',"LastVal":"'..v.LastVal..'"}'
and changed it to this and then a table.concat later:
table.insert(lul_json, '{"Id":') table.insert(lul_json, v.Id) table.insert(lul_json, ',"LastRec":') table.insert(lul_json, v.LastRec) table.insert(lul_json, ',"LastVal":"') table.insert(lul_json, v.LastVal) table.insert(lul_json, '"}')
Made a substantial difference as we know a dot dot string concat is very slooow; especially when chained from one string to the next. It may be even faster to not use table.insert but a straight
lul_json[count] = xyz count = count+1
So the luup.call_delay() test routine above can be helpful in finding errant plugins, etc.
Roger on the test window and using require: I have my thousand lines in the test window and another 500 line coming in from a require and all works fine!!
