    Image file for Domoticz running on a Pi with HGI80 drivers installed

    Just in the process of creating the image file for this.

    It's:
    - Dev build of Domoticz, release version (i.e. you can make changes to the source and recompile on the Pi)
    - HGI80 drivers added
    - The web server runs on port 8080
    - It uses DHCP to pick up an IP address (I assume people will want a fixed IP, but as we all have different RFC 1918 ranges - 192.168.*, 10.10.* or whatever I think it's easiest for most people to bind the IP address via their router).
    - SSH enabled
    - As released it has the standard password for the pi login, but you should probably change that.

    Can anyone think of anything I need to add before I make copies of this available? I'm probably going to share it via Dropbox, and only for a few days. I just think it might help some people.

    Oh, and hand up who's interested...

    Will the Domoticz server automatically restart on reboot?
    Will the Domoticz logs rotate?

      Yes, the service will start on reboot.
      I've done no configuration in Domoticz itself. It's a clean install. I didn't even add the HGI80 device (I simply made it available to use).

        OK, here's a link to the image. It's for a 32Gb MicroSD card.

        If you don't already have a dropbox account, when you click Download it'll try to sign you up for one. Look for the "No thanks, just download" link underneath.

        Let me know how you get on.

        I'll leave this live for a week or so.

          Thanks Paul. I've directly copied it to my Dropbox. Since I don't use Dropbox a lot, I can afford to keep it shared for longer. So it's available from this link here too.

            At a risk of sounding the dumb blonde , is this something I can use Paul?

            I take it that it tracks temps. I have a pi (but don't have HGI80).

            I did start to follow some instructions on here a while go but couldn't get things to work and gave up.

              I think a lot of people are in your shoes, which is why I made this!

              if you don't have an HGI80 you can add the scripting stuff to talk to the API - see https://www.domoticz.com/wiki/Evohom...ller_or_RFG100

                Has anyone managed to download this image. I managed to copy it into my Dropbox area but neither my link, nor Paul's will download. They both get to about 0.3GB and then stop.

                  Just downloaded your version Bruce - no problem, although it was a bit slow (as Dropbox downloads often are) - took about 6 minutes.

                    I too finally managed to download this into my network but it was hard work. Downloaded it straight on to my NAS, which is hardwired to the internet and even then there were multiple "Broken Link" error messages. Thank you to the man who came up with Download Resumes!

                      If you're struggling to download large files check the MTU on your network (clients and broadband router). That's often the problem.

                        Good point. I have a BT HH5 on Infinity so the MTU is not adjustable and is fixed at 1488. I need to make sure all the clients are set to that too.
                        There is something definitely wrong with my network and large files. Even though I thought I had downloaded the image completely, Winzip is complaining that the file size is incorrect.

                          Sorry if this is granny and egg sucking but use ping with the 'do not fragment' flag, and setting the packet size to determine the best MTU for the client. Don't forget to allow for the frame overhead.

                            Did that and confirmed that my MTU indeed needed to be 1488 for my NAS to connect to dropbox.com. It was previously set to 9000. Downloaded the file again via the NAS and this time the entire file came down without a problem. I've never needed to change that before and often download large files and have never had the problem. My pc wifi clients with the changed MTU setting to 1488 still gets stuck at 0.3GB for some reason.

                              9000 is jumbo frames. Needs the router to support them too.

                              As for the PC, maybe the frame overhead is higher? Especially if you have things like QoS enabled

                              Try

                              ping google.com -f -l 1488

                              Does it say "packets needs to be fragmented"?

                              If so, try setting the MTU to 1472.

                              Actually, before you do that try:

                              netsh interface ipv4 show subinterfaces

                              to conform that the MTU really IS set correctly, and hasn't defaulted to 1500 on the relevant interfaces.

                              P.
