OK, problem solved.
If anyone interested, here is recipe:
Update: you can add camera remotely, without being on the local network. Following procedure works no matter if you are local or remote
[ol][li]go to the https://dev.netatmo.com site and log on using your Netatmo login/password[/li]
[li]click on “our resources” on top of the page[/li]
[li]then go to “security” on the left side and click the “+” sign next to it[/li]
[li]from the list which will appear below, choose “Gethomedata”[/li]
[li]Find “Try this method by yourself with our TRY IT module” section and click the arrow pointing down below it[/li]
[li]The section will enlarge, leave all fields empty and click “Try it”[/li]
[li]New part of this section will appear below, you have to click the arrow on the left of the section "
body:[object Object]"[/li]
[li]New parts will expand, and you are expanding following ones (clicking arrows on the left): “homes”, "
[object Object]", “cameras”[/li]
[li]you’ll see as many sections named “[object Object]” as you have cameras (if you have one there will be only one, if you have 5, then there will be 5), no matter at which locations those cameras are placed[/li]
[li]find desired one (the name of the camera will be visible as “name” when you expand specific section)[/li]
[li]find camera link, described as “vpn_url”. Copy the link to clipboard without quotation marks at the end and beginning (but commas are important) and add /live/snapshot_720.jpg at the end. You should see preview from your camera.[/li]
[li]You need to get specific local link for the camera. To do so, you need to again paste the link you’ve got but this time put /command/ping at the end[/li]
[li]you will get something like: {“local_url”:“http://192.168.x.xxx/387e6c844929d3c83f08d335fa342f5d0",“product_name”:"Welcome Netatmo”}[/li]
[li]test your link by getting the part http://192.168.x.xxx/387e6c844929d3c83f08d335fa342f5d0 and adding /live/snapshot_720.jpg at the end[/li]
[li]If it works, you can set up camera in your Vera.[/li]
[li]Go to “cameras” section, click “add camera”, “IP camera (other IP camera)”[/li]
[li]Go through wizzard and click “Manually install the camera (advanced)” button[/li]
[li]Choose IP of your camera from the list[/li]
[li]Select “Other IP camera” in the “Manual Configuration” section[/li]
[li]“In camera link” field put all your local link to camera (so this which looks like: http://192.168.x.xxx/387e6c844929d3c83f08d335fa342f5d0/live/snapshot_720.jpg from example[/li]
[li]Enter your Netatmo login and password in the proper fields[/li]
[li]Click “test” to see if it works, and when yes, click “next”[/li]
[li]Tadam, your Netamo camera appears in your Vera[/li][/ol]
You will not have live preview, but still images refreshing on 30s-60s rate. Or you can refresh it manually.
Maybe there is a way to get live preview by chaging the part live/snapshot_720.jpg for another (maybe “mjpg”?)
