Homey Image Grabber app

Peke

Well i dont have much more info, i only know i used homeassistant before and there was the option for "digest authentication" and then the snapshot works.

Hope you have something on the links i gave you.

@JasperB you're hyperlink isn't working

@Peke which model do you have?

Here's a list of all the URL's.

Depending on your model, it's probably something like:
http://[IP_ADDRESS]/cgi-bin/snapshot.cgi?loginuse=[USERNAME]&loginpas=[PASSWORD]

Peke

Ah sorry i know the url,

http://[ip-adress]/cgi-bin/snapshot.cgi?loginuse=[username]&loginpas=[password]

This one works in my browser but i comes with a popup to enter credentials, i can say remember them and it works.
If i put the admin-password@ infront of it, "image grabber" doesn't make a screenshot. It comes back with the green checkmarker so it looks like it going good.

Veldkornet

Yup, if I use that site to generate the URL, it looks more like this:

http://[USERNAME]:[PASSWORD]@[IP_ADDRESS]/cgi-bin/snapshot.cgi?loginuse=[USERNAME]&loginpas=[PASSWORD]

Peke

Yes it works in browser http://[USERNAME]:[PASSWORD]@[IP_ADDRESS]/cgi-bin/snapshot.cgi?loginuse=[USERNAME]&loginpas=[PASSWORD] but with "image grabber" it doesn't.

I have the same issue with my axis cam. Works in browser not with the image grab app.   

Veldkornet

If you change the url to a static JPG image, does it work then?

if not, it’s your flow that’s not working. 

Peke

@veldkornet what do you mean?

Veldkornet

What I mean is, instead of the URL for your camera, use a URL like the below:

https://upload.wikimedia.org/wikipedia/commons/f/f1/Google_Blogs.JPG

Then, if your flows are triggered, do you get that image?

In essence, as I don’t know what all you have working and what you don’t, I’m just checking if the problem is actually grabbing the image from the camera, or if the problem is in the flow (ie, the image is just not sent)

Peke

Ah k i see, i also have a foscam camera and the image grabber works with the same flow with the foscam. it has to do with the digest authentication i think.

Jeroenvano

I am also confident that the issue is in the authentication as the flow works giving me a text push message to my phone.

As soon as I have some more time (very busy at work), this is one of the first apps I'm going to update, to support SDK v2 as well as using the official image tokens.

You are probably are of this but I tried installing the version that is on Github but it kept crashing due to missing nodejs modules. I added some manually but couldnt get the updated app to work eventually.

Peke

Any update on the authentication problem? wil your new version solve this?

Authentication methods have not been changed in the update. I don't have enough information about what is going wrong.

Hi, same problem here. With Foscam cameras: URL works in browser not with the image grab app. Using email sender app also by Jorden. This results in an email with x.jpg attached but x.jpg cannot be opened.
Would love to see this work again. Is there something I can do to trouble shoot this? Can I send you log files?

What model Foscam do you have?
I use it with Foscam without any problem. 

Eternity

I have exactly the same as @DrDoom. An attachment with x.jpg
Various older and newer Foscam camera's

DrDoom

I have the 2 Foscam FI9804W. Homey runs on latest stable 1.5.3. Mail Sender is 0.1.6 and Image Grabber is at 0.0.3.

Using this URL: http://[localIP]/cgi-bin/CGIProxy.fcgi?cmd=snapPicture2&usr=[USERNAME]&pwd=[PASSWORD]&;
(which works in a browser)
Using below flow to test (for who want to know it is the NFC tag of my sons Super Mario Amibo   ):

jorden

Can you try with http://[localIP]/cgi-bin/CGIProxy.fcgi?cmd=snapPicture2&usr=[USERNAME]&pwd=[PASSWORD] instead? Not sure but the extra characters at the end might cause troubles.

DrDoom

Changed the URL but alas. x.jpg cannot be opened. 33 bytes is also too small to contain picture data, I believe.
@Eternity : Do you use the same URL's?
Is there maybe a token URL form the web I can try?

Thanks for the quick response by the way!

jorden

If you save the x.jpg as a x.txt and open it in a texteditor, what does it say?

You can use any JPG file from the web to test with; for example:
https://forum.athom.com/uploads/editor/li/e9jximxjm2c3.jpg 

DrDoom

Renamed it to txt but that gave a lot of gibberish:

†Ûiÿý}Û^¼×M5ÓÏ<÷÷ ‹æâŸð† úèÇ'Ü‚'&

Using the web URL gives me also an unopenable x.jpg 

Veldkornet

The URL looks the same as the one I use:

http://<IP_Address>:88/cgi-bin/CGIProxy.fcgi?cmd=snapPicture2&usr=<username>&pwd=<password>;

Do you have a weird character in your user or password?

Eternity

This url works for one of my Foscam ip camera's:

http://IP:PORT/cgi-bin/CGIProxy.fcgi?cmd=snapPicture2&usr=XXXXX&pwd=ZZZZZ

This doesn't:
http://IP:PORT/cgi-bin/snapshot.cgi?loginuse=XXXXX&loginpas=ZZZZZ

DrDoom

The URL are indeed the same. No strange characters in the username/password but I will try a simpler password tonight. On the other hand I do not think the URL is the problem here since easily accessible URLs from the web also do not work. How about a good old reboot?

Eternity

I have it working again :-)

The url I use is: http://IP:PORT/cgi-bin/CGIProxy.fcgi?cmd=snapPicture2&usr=NAME&pwd=PASS

UPDATE
It's working for 3 of my 5 Foscam ip camera's (various types), so I guess I will have to use different URL's format for the not working ones. But, having it working is a nice step, the rest will be finding the right url.

UPDATE 2
My other Foscam camera's work too now, with url format: http://IP:PORT/snapshot.cgi?user=NAME&pwd=PASS


Two flows are used:

After an alarm, an image is grabbed and a Telegram is send:


Followed by this flow to send the screenshots via Telegram and e-mail:


Nice to know.. it is possible to use the same flow for sending multiple images (ignore the AND column, it's only for testing right now). For different screenshots I have set a delay of 10 seconds between the 'grabs' :

DrDoom

Great you got it working again! Did you change something in your setup? Or was it just finding the right URL?

In the mean time I have done a reboot of Homey. Did not help.

The first URL in the last post of @Eternity works for me in a browser. The second one does not, so I'm definitely using the right one.
Simplified the password of the account on the Foscam I'm using. Did not help.
Also created and used new account for the grabber on the Foscam with admin priviledge. Did not help.

Can somebody please use the Image Grabber app with a link to a picture on the internet that works so I can rule out any setting in my Foscams? Please post the link you use here. Thanks!

jorden

You can use any image, like:

Veldkornet

I just used your profile pic, came through just fine:

https://forum.athom.com/uploads/userpics/325/p79373ZDOO3HM.jpg

DrDoom

Ok, fixed it!

Instead of doing it in one flow like I showed in my previous post I did it like @Eternity in two flows; One for actual grabbing of the picture, and one for sending the mail. First tried it with my profile pic and after succes did it with my Foscams. Nice!
Thank you all for the effort!

@Eternity : One question left: Are you able to make a distinction between an image grabbed because of movement or an image grabbed because of the doorbell pressed?
