Domoticz

APP:
Version: 0.2.232 (7878)
Platform: Android 9
Plugin/Hardware: MQTT/Philips HUE

Domoticz:
Version: 2020.2
Build Hash: b63341bc0
Compile Date: 2020-04-26 13:47:55
dzVents Version: 3.0.2
Python Version: 3.7.3 (default, Jul 25 2020, 13:03:44) [GCC 8.3.0]
Hardware: Raspberry PI 3B, Raspbian Buster Desktop version

When changing the brightness level of a MQTT (Tasmota) light, one or more other lights (HUE and/or other MQTT lights) switch dimlevel too, even if they were off. Sometimes this also happens when changing the dimlevel of a HUE light, then other HUE/MQTT lights change accordingly.

This behaviour doesn't occur when controlling lights with the webinterface, only when using the app. I tested with the paid en free version of the app.

I tried disabling Events/dzVents/Lua -> same results
I tried a fresh install of Domoticz on another SD-card with only HUE and MQTT hardware installed and enabled -> same results
I tried resetting the app -> same results
I tried removing/installing the app -> same results

When I use tcpdump on the raspberry pi where Domoticz is installed to view the traffic from my phone to Domoticz (sudo tcpdump -vv -X src <my_phone_ip>), the following happens when I set the dimlevel for device 1144: So when changing the brightness of only one light, the app is sending the command for multiple lights with the actual light last

I've been at this for 2 days now and am currently at a loss for what to try next. Since it also happens on a fresh install of Domoticz there must be other users with the same problem?

_{edit: updated title}

Today I installed 8 shuttercontrollers at my friends home. The shutters are controlled by MQTT and are installed on a fresh domoticz. After installing the Domoticz Lite app on his tablet, the same thing happened again -> When changing the close-percentage for shutter A with the app, shutter C changes too, to the same percentage. When controlling shutter A via the website, shutter C does not change.

Since this is a new rpi, a fresh domoticz and an other tablet I am convinced there must be other users with the same problem. I know I am the common denominator for both sites so it could be a configuration/setup problem, but since tcpdump showed that the app is sending a command to multiple devices I still believe it's a bug in the app.

_{edit: typos}

My brother also has this problem..
When trying to dim one light a few others (seems random which ones) follow.
Using the web everything seems normal.

In the domoticz log after pressing only 1 light to dim once:

I experience the same problem.

The latest update 0.2.232 (7897) seems to have fixed the problem

Still have the same problem with latest version 0.2.232 (7897). Already tried reinstalling with the same results.

Bump,

Have the same behavior. When in plan tries Changing devices multiple devices changes..

I have the same issue but the developer is not really looking at this, even though I'm a paid subscriber and purchased the original premium.
Very disappointed

Will do another kick of this topic, in the hope this issue will be addressed.

Perhaps make a documented issue here: https://github.com/domoticz/domoticz-android/issues

Already open https://github.com/domoticz/domoticz-android/issues/644
Have asked repeatedly what is needed to troubleshoot, more than happy to get this fixed.
