OK - for those interested:

I accidentally deleted the L_openLuup.lua file, which is listed immediately above the L_ShellyBridge.lua, which was the file I intended to delete.

Amazing that everything else all still worked perfectly.

Love openLuup - it just keeps working perfectly.

I started looking at trying to add a gen4 Shelly device to the Shelly plugin via L_ShellyBridge.lua. The plugin is a little uncooked (no rudeness intended), so a bit of a rabbit hole for me.

All of a sudden no console pages available in either Firefox or Chrome. AltUI works perfectly and all the log files indicate no errors. openLuup still running everything works as it should - just no console pages.

I possibly screwed something up but any recently changes files show no problems. The original/ backup of L_ShellyBridge.lua was reinstated but still no console.

Bit stumped on this one. Not sure how to debug. Any ideas?

Bought some Crucial PCIe Gen4 NVMe M.2 SSD for $46 USD late last November and now in mid Feb, they are now $74. About a 60% increase in three months. And they have dropped a little in price of late.

Seems a case of AI computing is vacuuming them all up, plus some players have stopped manufacturing.

Just on AltUI:

The browser would be downloading any number of resources first time round from various servers. But I would have thought the majority of servers would be using some sort of cache control header combinations to the command the browser's caching. You don't need to be downloading jquery every time you hit a web page and I think it's unlikely that would be happening.

So I would have thought that the browser (for AltUI) could have cached most of what AltUI needed? What resource is the browser calling up that it can't download with the internet connection down? Maybe AltUI could have functioned but in some sort of reduced capability mode?

But yes the openLuup console, as I understand it, has been written to not rely overly on outside resources. Surprising akbooer could get it work!!

I had this problem a long time ago:

You need to set up the required files locally somewhere. On a local directory, NAS, USB stick, web server etc. You then have the responsibility of keeping them up to date. Some things may still not work like Goggle charts.

amg0 set up a variable in the AltUI plugin labelled "Local CDN ?" that can be used to point to the new local file source. So it's not hard to switch back and forth.

In normal operation (ie using the internet) this variable is blank. You can read amg0's doco from here at GitHub

The old forum discussion here.

"AK: Your best bet would surely be to register a callback handler to listen for messages on a specific address?"

Yep - that seems the most obvious method - just wanted to make sure I hadn't missed some other turn of events. With your own callback handler, you can clearly sort out any email encodings, etc.

On the Doco - Goggle doesn't seem to index github io pages. Seems to me you need to have some sort of URL redirect, that looks like say https://smarthome.community/openluup, that would get indexed? ie via the web server set up or similar.

Hello AK

Have been writing about the openLuup email server as I was tinkering with it the other day. One minor problem: it looks like the domain part of the email address eg ...@openLuup.local is case sensitive in openLuup.

Looking round the net, it suggests that the local part is case sensitive but the domain part is not meant to be. To keep things so they are more likely to work, it's suggested the email address should be totally case insensitive regardless. Refer to rfc2821 page 13 or search on the word "sensitive". Suffice to say I was using mail@openluup.local rather than mail@openLuup.local, so it didn't work for me.

Next challenge was that the file saved in /etc/cmh-ludl/mail has "Content-Transfer-Encoding: base64" so the body of the email was encoded:

Received: from ((openLuup.smtp) [ip_address_1]
 by (openLuup.smtp v18.4.12) [ip_address_2];
 Tue, 26 Nov 2024 14:21:22 +1000
From: "dali@switchboard" <dali@switchboard>
To: "mail@openLuup.local" <mail@openLuup.local>
Subject: Warning form R2E.
MIME-Version: 1.0
Content-Type: text/plain
Content-Transfer-Encoding: base64

QXV0byBXYXJuaW5nOiBDb2xkIHN0YXJ0IGV2ZW50

The above base 64 text translates to "Auto Warning: Cold start event".

Is it your preference to leave the saved files in the raw mode or would you consider translating the base64 text in the openLuup code base?

On a side note, does the reception of an email by openLuup generate some sort of trigger that can be watched. In the case above; the email represents the restoration of power after a power outage. I would like to know about that by the email triggering a "Telegram" notification on my mobile.

I see that the images@openLuup.local images@openLuup.local can be associated with I_openLuupCamera1.xml, which spawns a movement detector child. Anything similar for the other email addresses?

Now fixed in the Development branch.

The code in your link was messed up when they updated that forum some years ago. I've rehashed it to give it a chance of working but I suspect you may still have trouble getting it to work. Running it in the Lua test window would be your starting point after reading the
push over api doco.

Another alternative is to use Telegram with the Telegram plugin.

May be better to get a DIN rail high powered contactor and use a Shelly to flip that on & off.

AK. Was doing an openLuup install and the installer errored with:

openLuup_install   2019.02.15   @akbooer
getting openLuup version tar file from GitHub branch master...
un-zipping download files...

Running it manually gives:

I'm thinking the dkjson code URL has been changed. On dkolf.de there is a download link:

http://dkolf.de/dkjson-lua/dkjson-2.8.lua

and dkjson code also seems to be in GitHub (I presume this is the same code?):

https://github.com/LuaDist/dkjson/blob/master/dkjson.lua

I'm don't know what dkolf.de looked like previously but I do see the dkjson code has been updated as of 2024-06-17. Hope this helps.

Oh - and by the way the dkjson.lua file seems to have been downloaded OK by the installer - error or no error, so go figure.

Tried out the above start up code and it has done the job. Now have lots of Shelly based files that can now be plotted using Grafana. They all have the same retentions but so far that's not a problem.

Great - thanks very much.

Easily answered: Whisper Database Format

OK

You should absolutely not create any extra files in the Historian folder.

OK - assume it's all meant to be private to openLuup. Best not to mess with its own little world.

IIRC, the Historian substitutes / in the file names it creates.

However whisper.create (filename,archives,0) does not. The string

"whisper/0.10006.shellypro3em.em1/0/act_power.wsp"

is used as is.

Ultimately I would like to have openLuup save the data for any variable I nominate and it gets saved no matter what the variable is called. I imagime forward slashes could be replaced with say dashes (underscores are already in use by Shelly).

The openLuup instance where I have the em1/0/act_power.wsp variable does not have DataYours installed. You have said however that any files in a whisper directory will get updated. Is that right? I though the whisper directory had be specified in DataYours?

So a little confused on how "em1/0/act_power.wsp" or any other variable with slashes can be charted. I can see how having children set up for each device could be set to do this but ultimately you need to be able to plot any variable of ones choosing.

For example the Shelly Pro 4pm also measures power (very useful) but the variable is "switch/0/apower" ie a completely different layout.

Variables don't have to be picked off a list - they could just be manually set up by ruuning a snippet of code such as "whisper.create" as seen above.

Currently I have some Whisper files used by DataYours that been working well for ages and do what I want.

One of the files is called Watts_L1.d.wsp and uses this retention from "storage_schemas_conf" in openLuup file virtualfilesystem.lua:

[day]
pattern = \.d$
retentions = 1m:1d

Inside the actual "Watts_L1.d.wsp" file is a header like so:

         1,      86400,          0,          1
         84,         60,       1440

The 1, 86400 is one minute & one day (in minutes) as per the retention listed above. As a side issue I would like to know what the other header values mean ie what's the syntax here?

New challenge: I now have three Shelly variables named:

em1/0/act_power
em1/1/act_power
em1/2/act_power

with a device ID of "10006" and a SID of "shellypro3em"

And I would like to plot them using the Historian, just like I do with Watts_L1.d.wsp in DataYours. So I need a file in the history directory for the data. So I looked at doing this:

local whisper = require "openLuup.whisper"

-- Syntax:  history/0.deviceNumber.shortServiceId.variableName
local filename = "history/0.10006.shellypro3em.em1/0/act_power.wsp"

local archives = "1m:1d"

whisper.create (filename,archives,0)

Problem is that the variable names contains forward slashes, which are invalid filename characters. What to do?

Also should the retentions now be (to suit the latest openLuup software)?:

local archives = "1m:1d,10m:7d,1h:30d,3h:1y,1d:10y"

Also "shellypro3em" is not a "shortServiceID" as per those listed in "servertables.lua". So can "shellypro3em" be used instead? ie can both short and long service IDs be used in the above call to whisper.create?

Try getting the json and checking it here. Also may be a decoding problem for the currency symbol. Try changing the currency to one simple character. The a-circumflex symbol before the pound symbol looks odd. UTF-8 versus ISO-8859-1 ?

The code above before it is reformatted has ", at the very end:

Any other startup processing may be inserted here...\nluup.log "startup code completed"\n\n",

OpenWeatherMap's API changes: Some time back OpenWeatherMap decided to change their API billing practices. The old "One Call API" arrangements (1,000 API calls per day free) have now ended.

You now have to provide your credit card details, so if you exceed the free 1,000 API calls per day you can be charged. The provided API keys don't work unless you provide these details. Returned error message:

{
  "cod": 401,
  "message": "Invalid API key. Please see https://openweathermap.org/faq#error401 for more info."
}

However, if you just want current weather with no forecasts, you can use the "weather" call:

https://api.openweathermap.org/data/2.5/weather?lat=%s&lon=%s&units=%s&lang=%s&appid=%s

It's possible the Multi Station Weather plugin could be modified to fall back to this call, if it fails on the first call. As suggested here.

In my case, I've hacked the MultiStationWeather plugin code to use the "weather" URL at all times, as I don't use forecasts.

I've got a lot of Zwave devices inside walls, so I'm being using a Vera Edge as a Zwave radio bridged to openLuup. Works perfectly once you move everything else to openLuup. Just leave the thermostats on Vera and bridge to openLuup. Makes the transition a lot easier.

Hoping to see Zwavejs talking to openLuup via MQTT one day. It's certainly possible. In the interim it wouldn't be too hard to set up a couple of Zwave devices using the Virtual Devices plugin but thermostats may be a bit tricky.

Also got ZigBee2MQTT talking to openLuup (mainly Hue devices) and some Shellies - all works nicely. You can also use Reactor with it.

You can read the openLuup info here.

Have you seen this post?

Or is this in addition to the above?

Had a look at the latest development code. Got this:

Had to get the house back up and running, so we could watch the TVeee.

Commented out some code:

local function log (msg, level) 
  local dno = scheduler.current_device()
  -- local mute = devices[dno].attributes.log_level    -- 2024.04.12  add "log_level" device attribute
  local mute = "something"
  if mute ~= "off" then
    logs.send (msg, level, dno) 
  end
end

Could look further but had to get the house back up and running, so we could watch the TVeee. So best I can do currently!
