Let's Control It

Same problem here, i used tasmota, got the same error after 6hs.

Barb232

hello,

maybe this is a little help.

You are right. A few years ago i asked the support and became the same answer: „Der Sensor ist nicht selektiv und erfaßt nur einen Summenparameter aller vorhandenen reduzierenden Gase. Wir messen eine Widerstandsänderung und rechnen diese mittels Algorithmus in ppm CO2.“ And yes, the plot shows the ...

i cant find a documentation
i want to light (control) one or more of the LEDs of this board remotely in different colors each.
GIT version: mega-20180331

My control looks this way

I compared the plots against BME680, Voltcraft Raumluftsensor and MH-Z19 together an I am not really satisfied with the results of the bme680. Maybe a software bug, i used the adafruit lib 1.05. The 3 sensors laying next to each other. i am waiting for a espeasy plugin. :-) references: https://blog....

Barb232

Hello, i get the same readings as in your source. but i am doing a longer test at the moment and i compare the plots with a co2 sensor and voc sensor https://blog.moneybag.de/luftqualitaets-sensor-voltcraft-co-20-ein-erfahrungsbericht/ https://blog.moneybag.de/fhem-luftqualitaet-messen-mit-dem-mh-z1...

Barb232

Hello, i see, that u used also the adafruit library, I used version 1.05 i wrote a short blog post for testing. https://blog.moneybag.de/fhem-air-qualitysensor-bme-680-temperatur-luftfeuchte-luftdruck-ueber-mqtt-getestet/ With the readings of the temperature and voc i am not satisfied at the moment....

Barb232

just taken from the adafruit source (i said quick and dirty

), altitude is wrong.
I am just interested in gas, the other data arent so much interesting for me.

Barb232

Hi, Yes, the price is okay, and the delivery was fast. I just coded a quick and dirty version for the esp 8266 and MQTT this afternoon myself. I am watching the values of the sensor, using fhem and make a chart. I think your are right with the higher temperatures, 1 degree higher, pressure and humid...

Barb232

Does anybody know when P119 bme680 sensor moves from playground to live? The BME 680 sensor measures Temperature, Humidity, Pressure and VOC (air quality). And is available on a board from aliexpress for a good price: http://s.click.aliexpress.com/e/6UZzVJY Further Information BME 680 on a raspi: ht...

i think there is a problem with rules i did this On co2sensor#PPM >100 do Gpio,16,1 Endif and the log says 6707 : MHZ19: PPM value: 410 Temp/S/U values: 32/0/0.00 76709 : EVENT: co2sensor#PPM=410.00 76720 : EVENT: co2sensor#PPM=410.00 Processing time:11 milliSeconds 76721 : EVENT: co2sensor#Temperat...

thats are my practical results, too.
Thank you

I wrote a short blog Post in my Blog, works fine.

yes, i did this

Barb232

Finally, it works. i downloaded the document http://www.winsen-sensor.com/d/files/infrared-gas-sensor/mh-z19b-co2-ver1_0.pdf And i tried the method 8a (manual calibration) I soldered a button between GND and HD and pressed the button for 7 seconds waited 20 min with open window Results: values 395 p...

Barb232

i will do this tomorrow, thank you

Barb232

snip
- calibrate the sensor (leave it outdoors for 30 minutes and upload the sketch which does zero point calibration in setup() once or twice

snip

where can i find this sketch?

Barb232

ok, thank you. i will try that.

Barb232

other question: is the espeasy with this sensor now ok? I read in the documentation, that there are memory problems and i should use custom espeasy firmware. Where is that warning? ESPeasy is running just fine with the MH-Z19 sensor for almost half a year now. here: https://www.letscontrolit.com/wi...

I am using 5V (external USB plug).
it boots with 410 and after a few measurements it runs into 5000
i am putting a case over it to prevent sunlight

Barb232

i am measering always 5000 ppm, temperature values are ok.
What is the problem?

Barb232

i am using Domoticz MQTT for this and it works.
i didn't find MQTT - Import in 147, so lets try the 2.0 dev 10 version.

Barb232

hi,
i am using fhem too, and i wrote a short post in my blog.
It doesnt matter if its OLED or LCD1602

https://blog.moneybag.de/fhem-lcd-displ ... or-sds011/

Robin

Barb232

i just updated to dev 9 with OTA, it worked.
but: i used #systime# in my LCD1602 display to view the time, now it shows the online time of the controller.
does some variables changed?

Barb232

I am using v2.0.0-dev8 and the MQTT-Import Device with OPENHUB-MQTT and it works fine.
Is it possible to switch the Backlight on and off?

Code: Select all

mosquitto_pub -t /FeinstaubDisplay1602/GPIO/4/set -m 1  doesn't work for me.

Barb232

Hi Dominik,

can you send me a link from your manual?
i cant get it working the MQTT and the Candle (using MEGA EasyESP)

Barb232

Thanks RappaSan (Fhem Forum?), it finally works. Updated to R88.
There was a small problem with the missing pgmspace.h but now ok.

Robin

Barb232

hm. i just downloaded from github the newest version. Where do i find 2.1.0

Barb232

When i am using MQTT in my ESP8266-01 my string in Subscribe and Publish gets damaged after i press submit. %2F%25sysname%25%2F%23 %2F%25sysname%25%2F%25tskname%25%2F%25valname%25 my Wittyboard works fine /%sysname%/%tskname%/%valname% I tried with different country codec (utf 8 / windows) , no luck.

is it possible to build a button?

Hi, it finally works, i had several issues: Problem Power-Supply: it took more current than i expected Problem GPIO 0 connection: Maybe i set the startup to LOW so i got the startup into flash mode. BTW: i used the switch feature in the software. Wouldn't it be nice to select a "Button" fe...

Very very strange, if i am starting this with arduino Serial monitor it works! I have an accesspoint ESP_0 if i am starting this with an powersupply i haven't a AP.

Thank you for your quick help. I installed the easyESP system on my PC (i usually work with mac). I installed a esp8266 2.1rc from the library and i got something strange. The esp8266-01 got flashed but i see only a few seconds the AP, then the blue led lights off. then on for a time and so on. i th...

Barb232

Hello,

flashed an ESP-01 and another ESP-13 with the newest R78-Firmware (512k). Flashing with Esp-Flasher was ok, but after a reboot there are no accesspoints to log in.
Other ESP-Moduls like NodeMCU are ok.
Thank you for your great work.
