Cheapest remote access for my boat

Agreed. However, remotely configuring the wireless setup over which you are connected is likely to end in frustration

I used to have an ADSL router where you could reconfigure the network you were connected to it with. It did require a little care...

Besides, you'd have the same problem with the pi and its wifi link to the phone.

Can't quite see how that would happen, unless you were somehow changing the phone settings?

I leave mine on connected to the mobile for weeks at a time before it gets rebooted for an update or whatever.

Slight thread drift but there is an argument for having the Pi as it makes monitoring over the internet quite a simple exercise for the cost of a beer or two.

Yes thanks guys. According i think the answer is a pi (which i already have anyway) and a usb 3 g dongle. Leave it permanently on. I don't think it will use any data particularly so don't need to be able to turn it on and off. Then i use the remote3 (used to be weaved) service to log in to the pi from home. Then ssh onto the terminal of the edison.

 

[roblpm]

Actually a mifi thing might be easier even than a usb dongle on the pi.

 

[roblpm]

Actually one thing......

So I ssh from home to the pi over weaved. Now I have a terminal window on the pi. How do I then open a terminal session on the edison over a serial connection (over a usb cable)?

The remot3 daemon will use up a bit of data as it keeps in touch with home base .. I don't know if there's a regular handshake, or simply a few bytes every time the IP address changes, but it might mount up.

Off some random Internet post, says 2mb a month...

"When Idle Weaved devices send/receive about 250 bytes every 5 min."

I have now confused myself about how i am going to connect from the pi to the other box! On a pc i connect with putty as it allocates a com port when i plug in the usb from the edison. This then gives me a terminal session.

There are several options - Google's your best bet rather than listing them here [other search engines are available]

Ok. . . . . . . (bu everyone could use Google instead of posting on here....)

Command line putty to /dev/ttyUSB0?

dmesg on the pi will let you know to which port the Edison is connected. You can then use ssh/minicom/screen/whatever to connect to that port.

Yes, and then we can revert to sailing-related topics

Ok thanks! It is a sailing related topic though......!!

And people find these threads through google so it's probably a nice thing to do to add any bits which might help..

So since you're sorted with a Pi.......

Bit of drift, if you're running openplotter on your Pi (why wouldn't you be??), for 12 quid you can get one of these
https://shop.pimoroni.com/products/automation-phat

Openplotter has a configuration file for the voltage ADC which turns the voltage into signalk , it's also set up with an MQTT broker and talks to an external mqtt broker so if you create and account here
https://www.cloudmqtt.com/

fill in the details in the openplotter tab then make an action in openplotter ( or node-red) to send the value to mqtt, then you can make a funky node-red dashboard online at FRED, the online node-red -
https://fred.sensetecnic.com/

Now you have a nice graph of your voltage online from anywhere using next to no data, MQTT uses little. Or set node-red to send you an email if the voltage gets below a set value. The free version turns itself off if you don't log on for a day though.
Mine just had to be restarted >

.. such as add a camera and some sensors and check that Ophelia, for example, hasn't sunk your pride and joy:

Very nice

Probably well beyond my meagre programming skills, openplotter, mqtt & node-red open all these doors for the rest of us

I'd not heard of that, what does it give you over ssh?

 

[agurney]

It acts as a proxy and tunnel to the service running on the remote IOT device. You still use ssh.

 

[roblpm]

I'd not heard of that, what does it give you over ssh?

What would you ssh to from your pc at home? You would have to have a static ip address on the mifi thing and have ports open etc. I think the concept of the remote3 thing is that there is a third party server on the Internet. Your pi connects out to it, your pc connects out to it and they are magically joined together. Then you ssh.

Not quite.
For the weaved/remot3 service I use Putty to ssh directly to the Pi with a host name something like proxy43.yoics.net and port 123456.

I'd set up dynamic DNS and ssh to the name.
You might need a tunnel if there's a firewall or proxy in the way as you used to get with mobile broadband, but I thought that was a thing of the past.
