OpenTherm Monitor Program

That's not rubbish, it's the output of either test #2 or #3 of the diagnostic firmware. Go to File->Diagnostics and in the window that pops up press the enter key. That should stop the output and give you a menu with diagnostic commands. You may run other commands to verify the workings of the gateway. If all checks out, go ahead and load the gateway firmware.

When i setup an email server in OTmonitor to be able to send alerts, it complains "Can't read "sock": no such variable.". What could be the reason for this?

Could we also have a (configurable) CH water pressure alert?

Addendum: The above in when TLS is selected. On Plain the message is: No supported authentication scheme. The smtp server is the one offered by my isp. It requires no authentication. Running on Win8.1.



Thanks!

Copy/paste error on my part I'm afraid. If you want to fix it yourself, get the otmonitor source code and on line 234 of alerts.tcl change $sock to $fd, so you get:

Code: Select all

            tls::import $fd
            fconfigure $fd -translation crlf -buffering line
            smtpputs $fd "EHLO [lindex [fconfigure $fd -sockname] 1]"

I'll look into adding a water pressure alert.

Thanks, that helped. The alerts don't work with open relay smtp servers. I've commented out the

Code: Select all

smtpauth $fd $data $cfg(email,user) $cfg(email,password)

and now it sends emails just fine. Also hacked CH pressure alert into it.... (copied the roomcold related items and modified them for CH pressure). And made the limits configurable.

I need the CH pressure alert as my 1 year old Vaillant has sprung a leak in the heat exchanger (i think, it loses 750ml/h from one of it's drainage hoses) so i need to refill frequently until the installer comes round on monday)

As a raspberry pi newbie, can someone tell me how to install the monitor program on the pi, or point me to a manual.

tnx

Download it, make it executable, run it.
