Home Automation Domotica Forum Europe, Bwired Forum

We are busy with an ESP8266 Wifi controller who can do MQTT and have status update, keep track of this forum :) This is now more or less completed :) I posted a new topic in the LEDs forum for the firmware to allow this, as well as if you do not want to bother with doing this on your own - i can do...

This post is about an upgrade to the popular H801 LED Strip Controller available for <10 eur from Aliexpress: http://www.aliexpress.com/item/RGBWW-Strip-WiFi-Controller-1-Port-Control-200-Lights-Communicate-with-Android-Phone-Via-WLAN-to/32502007408.html?spm=2114.01010208.3.1.6VYraI&ws_ab_test=s...

I have used the example in the config app. http://192.168.1.16:2234/myservice?co2=%s&id=vAir When I used this in my browser nothing is come up. The device does not support inbound connections - that is - it will not act as a web server. It rather uploads data either to some online Service - eit...

just a quick status update: i had expected the that today i would get the PCBs for the two types of devices. Unfortunately today they told me that my order is going to be delayed by one week :( At least as a bonus - this means that i will have time to add also support for MQTT, so the new Firmware w...

The modules are quite sensitive to power supply and some connections and this is why it is better to use the pre-made boards like Wemos or Nodemcu. Apart from this it really works quite stable

it is in fact based on an esp8266 and some pre-soldered and configured sensors Whether or not make it compatible is what i want to understand. There are some alternatives https://www.kickstarter.com/projects/seeed/wio-link-3-steps-5-minutes-build-your-iot-applicat?ref=nav_search https://www.kickstar...

Hi Guys, In the discussion around the CO2 Sensor i produce, i got the impression that there is a lack of affordable WiFi-based sensors to plug into home automation systems. With this I mean sensors for temperature + humidity, pressure, IR/UV Light, Dust, CO2, Motion, etc. But also some Wifi Button, ...

Just a short update, how the device box will look like (for the one with just wifi and ndir sensor, and no oled Gauge) 20160131_125309.jpg https://www.youtube.com/watch?v=XMdT_6rbKfg The dimensions are ~ 57x57x28 mm In addition there will be one button on the top (in a future fw update it will do so...

As a powersupply is needed it would be great if you could include the Mqtt protocol
so 2 options, send with http or Mqtt
also options as send only when value is changed, and a heartbeat option

yeah.. right this things I will try to add next week

Are firmware updates possible? yes.. there are two firmware parts.. one is updated via serial port.. that controls the display, leds and triggers the data sending the other is updated over the air.. and it controls the wifi capabilities.. custom servers .. mqtt (coming soon) both are open source an...

Is it possible to buy this version without the casing? I would love to use these for my ventilation system. It is possible, in fact i will be able to sell it sooner, because i will need more time to design the enclosure. Unfortunately i cannot reduce the price too much, as i am anyway printing them...

For some reason i stopped receiving notifications that there were new posts, sorry. Thank you all for the interest. I appreciate it! I did some further tests with the NDIR sensor and it works quite well. I had to change a bit my PCB design though and order new ones. I expect them to arrive arrive ar...

Thanks, Just to clarify - the Sensor will Send the data to a server, and not work as Web Server, so that you can query it (at least for the time being) Of course i can provide you a discount The prices are on the site http://vair-monitor.com I can give you ~10% discount that is the Wifi device for 5...

One question: how accurate are your sensors (how are they calibrated)? They monitor what is the lowest CO2 ppm value read and assume this is 400 ppm. This is processed in 8 days cycles, where the lowest ppm value from the previous period is used for the current. The sensor is electro chemical and a...
