Domoticz on openwrt: setup gets deleted after restarts Topic is solved

[szakaria]

Hello,
I am a newbie. I installed domoticz on openWRT (in a TP-Link C7 V5 wifi router) using the command : opkg install domoticz. Any inserted setup (using the GUI) gets deleted after router restart. Where shall I dig? Thank you very much.
Regards
Zak

I finally solved this issue as follows:
1- I created a RAM disk as /var/log
2- I created the following links in /tmp/lib/domoticz/ :
domoticz.db-wal -> /tmp/log/domoticz.db-wal
domoticz.db-shm -> /tmp/log/domoticz.db-shm

By doing this, my statistics data are no lost after the router restart.

3- after each configuration, I manually backup domoticz.db file.
4- added a script that executes at boot and restores the backed-up domoticz.db file to /tmp/lib/domoticz/domoticz.db

Is there any reason why you want run Domoticz on a Router?

[szakaria]

The reasons:
1) I don't have a raspi where I can install domoticz.
2) I already have the wifi router at home with openWRT and running few services.

what hardware the openwrt is running on?

Domoticz uses a lot of resources.... it could be quite a bad idea to do so....

[szakaria]

The hardware is: TP-Link C7 V5 wifi router.
You are right for the resources usage.
I have the following services running: nginx (to host my web page), ddns (to make my router reachable from the internet with a fixed hostname), dhcp server, openvpn server, and domoticz.
Untill now, there is no issue related to resources utilization. Let's see what may happen when the load on the nginx and domoticz increases.

why don't you evaluate a Raspberry or a NUC?
low prices (35~60€) and great effort and reliability!

[szakaria]

sure, Raspi is worth a try.

Today I installed Domotiсz on an OpenWRT Router and ran into the same problem.
The folder /var is overwritten after each reboot.
Therefore, I edit the path in the file /etc/config/domotics
from /var/lib/domoticz/ to any other folder outside /var and /tmp.
For example /home/domoticz and copy the contents of the folder there.

Hello, I configured domoticz on the router, everything works fine, but when I enter my location coordinates, the present time of sunrise and sunset does not show correctly as well. what could be the problem?

[waaren]

what could be the problem?

Switched lat /lon ?

What did you set for lat / lon and what are the sunrise / sunset times (and where do you see them)?

[spot320]

the actual coordinates of my city latitude 42.488304 longitude 132.524088 sunrise 05:33 sunset 20:39. In home automation, the coordinates are as written above, but sunrise and sunset 19:36, sunset 10:40. what could be the problem?

One is dispayed as UTC and the other as local time.

[spot320]

do not understand what you mean? latitude and longitude are correct but sunrise and sunset are not in local time.

To what time zone is your Openwrt system set?
As it looks like it is in a different time zone as your location. They should be the same.
