Zwavejs2mqtt auto-discovery of rain meter

[mgugu]

Hi,
Just to report some strange behaviour regarding zwave auto discovery of a zwave rain sensor(Popp z-rain):
- 3 custom sensor devices in "utility" section
- 1 switch On/Off battery
- Battery level not reported.

In OZW all these data are packaged in single rain meter sensor in "Weather" section.
Bug ? Any idea?
At the moment my workaroung is to populate a virtual rain meter through nodered.

Bug ? Any idea?

We can only check when you share the following:

• MQTT AD CONFIG Messages
• MQTT Status update messages for the devices

The battery level should be part of the device/sensor and not be a separate device anymore (as far as I can remember) .

Right. Acctually he level is not reported at all by domoticz. Only the switch "battery is low"

I do not see any battery levels in the posted state updates... aren't there any related to these devices of other subdevices of this ZWAVE node?

It is in topic "zwave/8/128/0/level"

[jvdz]

Ah ok .... the config states its a Battery percentage device and then a simple level update is send.... got it...

You gotta love the multiple ways the HA discovery is implemented. Most send the battery level as a keyword in the payload.
This needs to be checked how we handle that.

It ceirtainly has a level of forrest gump-ness over it: Autodiscovery is like a box of chocolates. You never know what you're gonna get.

Do you mean that no standard exists for AD device configuration ?
That would mean that domoticz has to be re-compiled for each new zwave device.

[jvdz]

That would mean that domoticz has to be re-compiled for each new zwave device.

Not really, The issue is that the data can be defines in multiple ways and we "just" need to cover those options. The challenge in Domoticz is that it creates devices under hardware, so 2 layers. Homeassistant uses Entities and adds any value received (Sensor/Light/Cover/Sensor) within that entity to the list. Domoticz doesn't have this option so each needs to linked to its own device with it's own Devicetype.

[mgugu]

OK. Thank you jvdz for these clarifications.

[gizmocuz]

One of the reasons is that the m3/cubic meters was not yet seen (and thus not implemented) before

Could you post some values of

zwave/8/50/0/value/196609

Still questioning how we shall distinguish if this is a rain sensor ... could also be a water meter
isn't rain reported in mm (millimeters) ? (instead of m3)

Edit: please try beta 14048 ... Maybe you get a rain device, but the rainfall could be extremally wrong.. (multiplied by 1000)

[mgugu]

Could you post some values of

zwave/8/50/0/value/196609

Code: Select all

zwave/8/50/0/value/196609  {"time":1641760938642,"value":0.075,"nodeName":"rainSensor","nodeLocation":"Outside"}

value is the counter in m

Code: Select all

zwave/8/49/0/General_purpose  {"time":1641760937360,"value":75,"nodeName":"rainSensor","nodeLocation":"Outside"}

value is the counter in mm.

Still questioning how we shall distinguish if this is a rain sensor ... could also be a water meter

May be presence or not of topic rainrate

please try beta 14048

Will install last beta and let you know

[mgugu]

After beta update :

Sensor correctly put in "Weather" now.
Default title is not correct (not cubic meters but mm)

Looks OK, BatteryLevel is not set but may be it is needed to wait an update.
We are on the good way

Hello everyone,

The subject of the battery level not reported is always present in my Domoticz.
Do you know, if some actions are made for this ?

Thanks.

This modules works fine in OZW and zwavejs-ui, but AD integration in Domoticz has never worked properly in my case.
Instead of AD, I use a dummy rainmeter populated directly by Node Red

[Romain2022]

With OZW, the battery level is not reported in Domoticz.
Am I the only person with this problem ?

[JackD]

I have the Z-wave POPP rainmeter, and it works fine with OpenZwave in Domoticz, including battery status.
But I am not on the newest latest beta, I run beta14957.
Did you set the "Wake-up Interval" for the rainmeter correctly?

[Romain2022]

Hello,
The wake-up interval is set to 240 seconds for me.
Where do you see the battery status ?

In the hardware controller screen, the column "battery" is empty :

[JackD]

You set the wake-up interval very tight, this will drain your battery very fast, but you won't know because you don't see the battery status
But clearly it is not a to wide wake-up interval setting. I set mine at 14400seconds(4 hours).
Works fine here with beta14957, but it is possible that with the newest beta Domoticz Open Zwave is finally "broken".
Open zwave is depreciated so it is a distinct possibility, go back to my version beta14957 and you will know if this is the case.
beta14957 works fine here, see my screenshot, my battery is at 80%

If open zwave is "broken" than you can try Zwavejs2mqtt or use a older Domoticz version.
