candle-manager-addon's Issues

Arduino CLI not working in mozillaiot/gateway Docker container on Raspberry Pi 4b (ARMv7)

I posted this issue in the docker image repo (WebThingsIO/gateway-docker#42), but have since found more info on the problem. The arduino-cli that comes pre-packaged in the Candle-manager-addon does not work within the mozillaiot/gateway Docker image (which is based on node:12-buster-slim). The workaround for me was to download the arduino-cli from https://arduino.github.io/arduino-cli/installation/ and update the SHA256SUMS file (using sed).

Here's my docker create/startup script that installs the addon and performs the above workaround.

Candle Manager does not seem to work anymore

Hi,

unclear why, but after 2 attempts from scratch, the issue can be repeated.

After adding the Candle Manager v1.0.4, and clicking on the "+" in the empty "Things" menu/screen, I get a message of "No new things found ..."

A new menu entry "Candle Manager" has been created in the menu (just before "log out"), but there is no option to add anything there.

Note: I loaded a version in November of the Candle Manager, and while I had some issues, it allowed me to create the receiver and a plant sensor. I am unable to get to that point now however (I am using the same Raspberry PI).

Thanks,

Candle manager doesn't seem to work

I cannot start the candle process
I installed the webthingsgateway on my rpi2 b.
I installed the candle manager addon
I configured the addon
The candle manager is a separate tab in the webthingsgateway
However I when I run the add things step candle does not show up at all.
I have tried without connecting the nano-rf and with the nano-rf connected.
I see this

The candle manager tab is completely empty

webthings 1.0 addon installer points to old version of candle manager

When trying to installing the candle manager addon in webthings the addon repository points to an unavaible and old release

I updated mozilla webthings to webthings.io so the culprit might be there.

checksum failed for candle_cleaner.ino

The candle manager addon crashes on my raspberry pi.

reimaged the sd card yesterday, and reinstalled candle manager and it worked untill today.

Showing ERROR for http requests returning 200 (OK)

The terminal output is full of "errors" like this:
2019-11-24 11:24:35.932 ERROR : Candle-manager-addon: - - [24/Nov/2019 11:24:35] "POST /serial_output HTTP/1.1" 200 -

As far as I know, http 200 is OK and not an error.

Candle Manager needs python requests module but does not install it.

After adding the add-on "Candle Manager" in the WebThings Gateway the terminal output will show errors "requests module not installed". A pip3 install requests (as the user running the gateway) and restarting the gateway after this will solve this.

Alarm-clock install fails due to SSD1306AsciiAvrI2c

When attempting to install the Alarm-clock, the install fails due to a dependency on SSD1306AsciiAvrI2c, a submodule of SSD1306Ascii. SSD1306Ascii is installed correctly, and searching for SSD1306AsciiAvrI2c just suggests the short name. The file SSD1306AsciiAvrI2c.h is installed at /home/pi/Arduino/libraries/SSD1306Ascii-1.3.0/src.

Any help, please?

Cross-compile rather than bootstrap

The addon-builder now has support for cross-compiling Python add-ons for various architectures and Python versions. It would be helpful to use it rather than bootstrapping on target in the background for a (long) time before being able to actually start up. You could even selectively include the property arduino-cli binary in your package, to make it smaller. I've done this for the Eufy add-on, as an example.

package.sh change: WebThingsIO/eufy-adapter@5cd3c3c
addon-builder change: WebThingsIO/addon-builder#49
addon-list change: WebThingsIO/addon-list#817

Candle Manager Page fails to load

For some reason when I try to access the candle manager page it gives me a ERR_NAME_NOT_RESOLVED error after it says "Sending request info to gateway.local" And when I change the default name in settings for the gateway it still says its sending request info to GATEWAY.local not the name I set it to, also this has been happening with anything that ends with ".local", it always fails to load the page, Ex: The musicbox program will want me to go to musicbox.local and it will give the same error.

Candle Manager cannot be loaded due to https mixed content restriction

Type: Bug
WebThings Gatewaz Version: 0.10.0 (on Raspberry Pi 3)
Candle Manager Version: 1.0.4

The WebThings Interface is transportet via https, the candle manager on port 8686 is loaded via http. In Chrome this is not possible and leads to a disfunctional User interface.

Error output from console:

Mixed Content: The page at 'https://xxxxxxx.mozilla-iot.org/things' was loaded over HTTPS, but requested an insecure resource 'http://xxxxxx.mozilla-iot.org:8686/'. This request has been blocked; the content must be served over HTTPS.

The behavior is observed when trying to reach the local ip address, the dns (gateway.local) and the registered sub-domain (x-ed out in the log).

Entering http://subdomain.mozilla-iot.org:8686 to adressbar manually works and starts the Candle Manager. Adding devices this way is possible.

Signal-Hub Menu Doesn't Do Anything

I created a signal-hub with a touch-screen. Upload was fine; added as a "thing" fine.

However, when booted up, the touch screen shows a Menu button that doesn't seem to do anything. It flashes briefly when touched but nothing else happens. I assume that is not the expected behavior since I can't really find any description of where one is supposed to go from here, but based on photos I've seen, there appear to be menu options I can't get to and/or a "listening" screen?

And just to make sure I understand—once the signal hub has been added as a "thing" it no longer needs to be connected to the pi by USB correct? After that it should communicate with the Receiver using the Nano RFs right?

A simple example of recording / playing back a signal how what that looks like it terms of creating a webthings rule would be extremely useful even if only to make it clear when something is wrong...

details:
I suddenly crashed, and so here is what I did.
I removed all other addons, reinstalled the candlemanager addon. removed all 'things'
No joy.
I will now retry installing the mozilla framework on my raspberry pi

$HOME not defined on Ubuntu install

After belatedly realizing that my pi was ARMv8 and only being identified as ARMv7l because Raspbian is only 32bit, I reimaged it with Ubuntu Server 20.10. Installed webthings-gateway (which was fine). However, Candle Manager couldn't download anything because a $HOME location was not defined.

I ended up working around it by adding a declaration in the webthings-gateway .service file.

USB Scan not detecting arduino

I have an Arduino Uno, and Raspberry PI 4.

I have followed the instructions, and it just seems to not be able to detect the arduino when it is connected.

I have tried using a different USB port, rebooting the Pi and reinstalling the addon, when I check the network tab in Chrome, I only see this as a response in the UsbScan request:

{
"port_id": [],
"state": "stable"
}

arduino-cli not found

New user, trying to setup Candle for the first time and trying to create a Candle Receiver—just keep getting an error on "Libraries" that "Downloading required libraries failed".

I think it has to do with these log errors:

I notice that the repository doesn't have folders for "linux-arm" at all and on the pi, the arduino-cli/ folder is completely empty.

Edit: my pi is an arm7l and I'm just using the current WebThings Raspbian image. So I downloaded the linux-arm7/arduino-cli and put it in place... "Libraries" was successful and now "Compiling" is failing with:

2021-02-03 16:12:00.123 INFO   : Candle-manager-addon: command = /home/pi/.webthings/addons/Candle-manager-addon/arduino-cli/linux-arm/arduino-cli compile -v --fqbn arduino:avr:nano /home/pi/.webthings/data/Candle-manager-addon/code/Candle_receiver

which seems significantly more challenging to work around than the last problem.

Or perhaps not. Ran:

arduino-cli core install arduino:avr

Now "Compiling" is successful but "Testing" fails:

Manually compiled the Candle_cleaner and that seemed to let it proceed and complete.

images directory missing

package.json lists a couple files in images/, but that directory does not exist in the repo.

Testing error on new device

Candle Manager installed correctly.
Candle Receiver installed correctly.
Up to there everything works OK.
Created a "temperature and more" device.

When installing the new device, the process stops at testing with an error message.
If I disable the "MySensors" add-on, there is no error but then the device is not recognized at the "things" / "add" phase.
