MCO Home A8-9 and Z-stick Gen5+

nkatsaros443 · November 14, 2022, 1:12pm

Hi everyone,

First of all, I’d like to express that I’m quite a newbie to the HA platform, so it is highly probable that I might be unware of some fundamental details at the moment. I will try my best to explain my issue, though.

Me and a colleague have set up an RPi3 with HA and Z-Wave JS. We are using an Aeotec Z-Stick Gen5+ as a gateway, in order to collect measurements from different sensors (a couple of Multisensor 6 ones, an MCO Home A8-9 and a POPP Z-rain). The sensors have been added as devices through the Z-Wave JS absolutely fine (or at least it seems so). I’m able to receive data without a problem.

Now the strange part. Although I get measured values from the MCO Home (and I’m able to cross-check them, since it has an LCD screen), I just can’t get the CO2 level to be transferred correctly. It is always stuck to zero. Data are received per the required interval without a problem. I can see the Z-Wave JS logs that the value read is indeed zero. BUT, the sensor itself displays non-zero values (in fact, around 1500 ppm, as we are in an office with a lot of people). The strange thing is that the rest of the values are read and updated correctly. What I’ve tried so far:

Adjust the settings in various ways (timers, delta thresholds etc.)
Restart the sensor, the RPi, plug the Z-stick to another port

To my understanding, it should be an issue between the Z-stick and the sensor…But the reason it affects just one measurement is still unknown to me. The only option that I have left is to delete the sensor from the network and re-configure it…but I can’t think how it will make a difference.

Has anyone else had a similar experience/worked with sensors from MCO Home in the past?
I attach the figures showing the problem and some of the Z-Wave JS logs.

Hello.

Im in an identical situation with both hardware and software. And i cant also get the CO2 data even though the sensor reads and displays the values on its LCD screen.

Have you found any solutions?

Hi Gabi,

Actually yes, I forgot to post the fix here. It is a hardware issue. I contacted MCOHome support and they sent an STM firmware update, which needs to be added to the sensor through an in-circuit programmer. Bear in mind that it requires some experience with hardware.

Thank you for the reply.

Can you advise me how to implement this update. Do i require specific hardware?

Thanks in advance!

You need to request the update file from MCOHome support, identifying the issue and the serial number of your sensor. Then you will need an in-circuit programmer as in the photo below.
