Thanks for your reply. Yes, we could update to remot3. We plan to update to an commercial account, but there is another problem : price.
If I understand, new price with remot3 is $3/ Month per device. It was $8 for ... 100 devices with Weaved... Am I wrong ?
I must admit we're looking for an other solution, Weaved had perfect price and functionality for us. Remot3 is too expensive, and even if updating software is easy, it's a waste of time when everything work.
Why not offer a simple reverse SSH for cheap (Weaved), and a most expensive with lot of fonctionnality for who need it (Remot3) ?
