Help. Domoticz combines the DHT and BMP180 sensors

[sindrome73]

Hi, I'm trying to assemble a mini Weather station, consisting of a temperature and humidity sensor (DHT22) and a BMP180 pressure sensor.
But Domoticz, in addition to the problem of combining sensors, after a while no longer reads the values sent by the Node.
Is there a way to vitar that domoticz combines sensors ??? I also tried to look, but it seems like a Domoticz problem

Hello,

did you have a look at this thread ?

Hi Goodmorning.

I had already read this discussion, but still does not indicate a precise solution from what I understand.
In the end, somehow I managed to show Domoticz the DHT22 and BMP180 sensors. In a united way, but able to update, because most of the time creates different sensors between Teperatura Pressure and then even if the data arrive from the node, they are not updated.
Surely all this is a problem of Domoticz, which should try to solve !!

Let's see if others can help us .....

I had the problem of combined sensors too, but usually once the devices are set in domoticz they stay that way even if I have the unused single sensors in the device list

[sindrome73]

The problem is that when multiple sensors are generated, the node sends the data, but does not update in domoticz

[gohan]

I never had that problem, if data are not updated usually it means there are unused devices that get updated

[sindrome73]

In practice it happens that with a node composed of DTH and BMP180, it creates 4 sensors, as follows:

• Only one Temp
• One Temp / HUM / Pressure
• Two for the pressure .....

The data reach up to Domoticz, surely, I see them updated in the HARDWARE tab, but then they do not update ..... or happen that some are updated and others are not of the 4 created.

However, the behavior in this sense is strange, and I think it is certainly a Domoticz problem.
Or at least the Domoticz Development Team should give the possibility to manage how to use the sensors, whether to combine or not

[gohan]

it is an open issue from some time in the Domoticz forum. If you want to try, assign a different node id to the sensor and see what happens when it creates it brand new

[sindrome73]

If this is the case, I started from node ID 99 and arrived up to Node 67, doing tests .... :sweat_smile:

[sindrome73]

We hope that in some way the user is given the chance to decide whether to combine the nodes
