Hi Manuel,
I'm Andrea Reginato, CEO of Lelylan. First of all thanks a lot for writing us.
I'll go directly to the point. Right now Lelylan works on the cloud, and without an internet connection you can't do that much. On the other side there is a big room to experiment new solutions and I've two ideas I would love to propose for two reasons.
1. The first one is the i simply LOVE the idea of a tech overlander camper. Really!
2. The second one is that would be interesting for Lelylan to work on an "offline solution" as a side project.
That said, here are the two ideas I've in mind.
First Idea
The first one is to install the whole Lelylan infrastructure locally. Lelylan is based on microservices (mix of Ruby and NodeJS apps) and uses quite a lot of resources, but we would love to try to make it live on a Raspberry 2. If we're able to make Lelylan live on a PI2, then you could have the whole Lelylan infrastructure locally, and make it accessible through WiFi or Bluetooth solution. This would need some time to be made.
Second Idea
The second one is to work at a lower level. Lelylan API can be split in two API levels.
- Developers API - High level API which offers all the functionalities related to control, monitoring, realtime, functions, statuses and more.
- Makers API - Low level API which offers the basic services to control and monitor a physical device.
A solution could be to use only the low level API and make up an app that works on them. The functionalities you could have would be limited, but enough to control and monitor your devices. In this case I would use Bluetooth.
Both of them are just a proof of concept and they need to be validated before starting, but, I wanted to share them with you. If you have the time to experiment with us, we would love to support you on this crazy adventure :) I would also love to know more about your experiences, to better understand how far I can move with tech explanations and eventual idea.
Have a great day.
See ya!
