[MyDomoAtHome] Support thread

[mcwieger]

Don't have a clue...

It was stable, but after updating to DSM 6.1.7 and MDAH 0.2.39, it's not anymore. Do you recall what you changed when you resolved the issue mentioned above?

[epierre]

not that part of code, I just did add a test on one device type...

[mcwieger]

Hi Emmanuel, I think I found the cause for the 'Unexpected end of input' error. I found out that one of my children had removed a z-wave dimmer from the socket (one I don't use very often). After I plugged it in again, MDAH has been up for several days again. The device that was removed is on my Imperihome dashboard.

My hypothesis: Imperihome or MDAH is doing some kind of periodic polling on all devices. If a device or Domoticz does not respond (properly), MDAH can't handle the input and stops.

For me it's clear what to do now, but it may be worth investigating this behaviour, to see if there's a cleaner way of handling devices that aren't available.

this is something new for me, but this is not MDAH, since the message is related on data sent from todomoticz to MDAH, and MDAH reacts unextectedly... on synology there is no forever process (we have on pi) possibility, maybe catching the exception would do the trick.

Thanks for the proposal.

When I ran the commands in 2 steps so first " wget -qo - http://www.e-nef.com/domoticz/mdah/gpg.key | sudo apt-key add - "

=> I got " gpg: no valid OpenPGP data found."

The existing gpg files were deleted first from the /home/pi directory

New shot here on a new RPI3B+ machine with Stretch version but same issue again ... " gpg: no valid OpenPGP data found."

The gpg.key file is downloaded in /home/pi and can be opened using nano

I do not know really what is wrong here !

BTW the readme.cmd file has to be corrected for "wget -q0" , to be replaced by "wget -qo"

[gerardosamara]

I did a new mdah 0.2.39 install with the last beta V3.9673 and it worked as per your readme.rd !

Testing the installation
Check in a browser it is running
http://gateway_ip:gateway_port/
From there you'll get the following links in the browser.
Check the domoticz is accessible from the hosting machine
curl http://domoticz_ip:domoticz_port/json.htm?type=devices&filter=all&used=true&order=Name
Check the MDAH returns the result from the hosting machine
curl http://gateway_ip:gateway_port/devices

Now I must complete with the integration with Imperihome

[timeclypse]

I installed the Domoticz on Synology as well as the MyDomoAtHome using the package as instructed here.

However, im having trouble securing MyDomoAtHome access to Domoticz.

The port 3002 is now wide open, and theoretically, everybody could access the MDAH.

I read in this topic that using config.json you can secure it all, but whatever i try (SSH) i can't find the folder where syno stores all of this.

Did someone manage to secure MDAH successfully on Synology lately?

Running latest stable Domoticz 4.9700, suddenly today my http://IP_rpi:3002 works but my IP:3002/devices does not work. Any ideas?

[EdddieN]

Following this to the letter: https://github.com/empierre/MyDomoAtHome and a curl http://IP:3002/devices gives me an empty response.

I read it was some recent changes that did mess up this but was fixed on the latest MDAH release? Is there anything in particular to look for since I get no improvement.

Not a solution but I have two RPIs at home, so ended up installing from fresh on one of them and pointing to the Domoticz install. Now it works (not on the original one that didn’t work, I imagine it will be some mix of files that I do not understand...)

From what I can tell the mydomoathome service isnt running. the only problem is I dont know why.

Hi folks,

I have MDAH working well with domoticz and Imperihome, but I'm seeing quite high CPU usage from the 'node' process and as I have intermittent delays in devices responding to commands from domoticz, I'm concerned that node's CPU use might be part of the cause.

Node is varying between low CPU use, 1~5%, and 50%+, occasionally even higher briefly. It settles at <2% the majority of the time but ramps up to 30%+ for a couple of seconds, every 15~20 seconds. The machine is an Intel Z8350-based box with 4GB RAM, should be more than powerful enough for the job. Ubuntu 18.04. Latest versions of everything - just built the new box and moved the system over today.

I have four tablets running Imperihome; most of them are asleep most of the time so I wouldn't expect the Imperihome refresh requests to be causing such high or frequent spikes in CPU. Is there anything else that could cause node to be burning up a lot of CPU? Any debugging worth me trying?

Thanks!

Is there any way to control how much MDAH logs?

Mine wasn't logging much at all, which was fine, but since I added some dummy selector switches to domoticz, MDAH is filling syslog with a load of info about them every 5 seconds! I was concerned that this might mean that it's having a problem with them, but the log entries seem to be just informational. That seems entirely unnecessary.

Example of log lines below. I'm seeing this pattern continuously - two sets of the same entries, about every 5 seconds.

Any way to stop this? Is it indicating a problem?

Negative values showing as positive in MDAH. Apologies if this has been reported already, but I couldn't find it.

I have a custom sensor in Domoticz, which shows sun altitude. After sunset, this has negative values, but these are showing as positive in MDAH (and Imperihome).

E.g.,


MDAH:
