Re: CCS811 Air Quality Sensor and ESPeasy

Hello TD-er Once again many thank for your help. This is really very kind. I always forgot the I2C scan under tools. Scanning doesn't find any device either on 0x5A nor on 0x5B but I changed the settings and enabled "Force Slow I2C speed" and suddenly I had TVOC: 0.0 and eCO2: 400.0. CCS88...

CCS811 Air Quality Sensor and ESPeasy

Hello all I installed Atom and PlatformIO but I wasn't able to compile an own build with plugin for CCS811 (P090). I realized then, that the sensor CCS811 might be supported in testing build according to the plugin list. https://www.letscontrolit.com/wiki/index.php/Official_plugin_list I then instal...

Re: SI7021 and BMP280 on same ESP8266

Thank you all I managed to get up and running my BMP280 on a second ESP8266 with brand new firmware :D. I'm very happy with this. Maybe I will try to have some sensors in parallel but for the moment that's fine for me. Next project is now CCS811 Air Sensor, but it seems that it isn't supported by ES...

Re: SI7021 and BMP280 on same ESP8266

Hello Thank you very much for your very fast help. I will try this for sure and connect the sensors in parallel. Do I have to use a separate GND and 3.3V for each sensor or can I connect them to the same pin? I'm using such an old build because I didn't touch my running esp8266 for a long time (neve...

Re: SI7021 and BMP280 on same ESP8266

Hello Ath and Eisbahn Thank you very much for your quick answer. Now it's getting hard for me to understand what you're talking about. The physical connections of the two sensors on my esp8266 are the following. SI7021 ESP GND GND Vin 3,3V SCL D1(GPIO5) SDA D2(GPIO4) According to https://www.letscon...

SI7021 and BMP280 on same ESP8266

Hello I'm not an expert in electronics but managed thanks to ESP Easy to attach a SI7021 for measuring temperature and humidity together with openhab. Now I also attached a BMP280 to mesure the pressure. Unfortunately I don't get any data from the sensor. Maybe there is a GPIO conflict but I really ...
