Proposal for new device in Domoticz Topic is solved

[HoogendoornJH]

I have a Senseair tSense CO2-meter (https://senseair.com/products/tsense/tsense-display/) which sends its data via a USB-port to a program that shows and logs de CO2-data.

Is it possible to add this device to Domoticz?

[Toulon7559]

At the Senseair-website reference is made to a ModBus Interface description (TDE0103.pdf).
To be checked how this description for this device matches with Domoticz, either by plugin, or by script.

According to productsheet PSP3488.pdf also analogue outputs 0~10V available:
easy, but less direct & (possibly) less accurate, because ADC required to read such signals.
Also translation needed to get readout in PPM from the ADC-value.

[EddyG]

It is already present. Type Air Quality, Voltcraft CO-20. Unit is ppm.
Now find a way to convert your data into this sensor. Node-red?

[HoogendoornJH]

Thanks for your responses.

EddyG, I assume that by "type" you mean "hardware type"? However, I cannot find a type "Air quality" in the hardware list.

[EdwinK]

You need to search for voltcraft.

[HoogendoornJH]

I am sorry Edwin, but I see neither Voltcraft nor air quality in the hardware list.

[EdwinK]

You can find it there.

Maybe it's just in the beta version of Domoticz.

I am sorry Edwin, but I see neither Voltcraft nor air quality in the hardware list.

First add a 'Dummy (Does nothing, use for virtual switches') type hardware.
Push the highlighted [Create Virtual Sensor] on the just created hardware.
Select sensor type Air Quality name- and create it by pressing OK.

It will show up in the devices tab like the ones below

OK, I did, but how do I link it to the SenseAir CO2-meter?

Via an API call or MQTT or mySensors ? Either direct or via a broker like Node-Red

[HoogendoornJH]

You can find it there.

Mmm, strange Edwin. I upgraded to the latest version, but do not find the Voltcraft in the hardware list.

Have you tried clearing browser- and appcache (different things) ?

- clear appcache
Chrome: chrome://appcache-internals/#
Firefox: https://support.mozilla.org/en-US/kb/storage

- in www/js look for domoticz.js.gz, if its there remove it, (KEEP domoticz.js !! )

- use incognito mode using
Chrome [control] [shift] n
Firefox: [control] [shift] p

[HoogendoornJH]

I performed your suggestions (did not find domoticz.js.gz), but still no Voltcraft.

Ah, yes, what a pity. Anyhow, thanks for the support.

By the way, I have a Raspberry Pi operational. Would it be better to have Domoticz running on a Raspberry Pi?

Probably very subjective.. But Yes

[HoogendoornJH]

Any idea what the advantages of running Domoticz on a Raspberry Pi in stead of Windows could be, apart from a possible antipathy for windows (and access to Voltcraft)?

I only have Windows on my desktop and laptop and they are not powered 24/7 because of the energy usage.
All other reasons are as said subjective and related to my lack of knowledge of the Windows toolsets and my preference for opensource + the tools / possibilities of Linux.
In fact I have domoticz on Windows, Synology, Raspberry Pi and Intel NUC for test and development and my "production" domoticz is on Intel NUC.

[HoogendoornJH]

OK, thanks for your opinion, waaren. May be I'll give Domoticz on the RasPi a try (the most difficult thing being the handling of USB ports). Actually, I am more used to a Windows environment and apart from a few remarkable things (which I will post soon), Domoticz works quite well under Windows (running 24/7 on a Surface 3). In general and as far as possible, I share your preference for opensource.

For what it's worth: a little Windows programme that came with the Voltcraft CO-20 USB stick is still downloadable from the Conrad website:
