@mister_ik You can use something like this - it works with a lot of languages

http://voxcommando.com/home/

@tripy yes, you are absolute right - you need to set the flash Mode to DOUT for flashing the newer SONOFF generation (the SONOFF's with the hidden green LED).

@gloob You can also flash first the Wemos with the "eraseEEprom.ino" from the Arduino sketch examples before you upload the gateway sketch ;-)

@Nca78 Thanks for the explanation - and yes, I'm also still waiting for the ESP32

@NeverDie To connect to the router take only 1-2 seconds for my wemos devices (static IP), but ok - maybe this is to long.
I think for a switch, it can be run all the time - or do I misunderstand something

@NeverDie Itead said this chip is also for creating wearaible devices - so I think it is possible to use it with batteries. The ESP has a deepsleep function but I have no experience with it and don't know how it works - sorry. I have only "hacked" the Sonoff touch wall switch to use it without the terrible cloud app - I don't use it with the mysensors stuff, but maybe it is possible to use such a switch as ESPgateway node (the chip is powered with 3.3V) and we can try to upload the ESPgateway sketch on the switch.

@Nca78 I have tested both types of switches (EU/US) and they have both the same components inside - so maybe the EU wall switch will fit because it is even smaller. The price for such a switch is amazing (15$), but it is not glass on the top it is acrylic plastic.

@NeverDie
Do you noticed also the PSF-A85 and PSF-A85 boards on the itead website?

https://www.itead.cc/wiki/PSF-A85
https://www.itead.cc/wiki/PSF-B85

These boards contain the new ESP8285. I have seen this ESP8285 (ESP8285 internal Flash is 1MByte = 8Mbit) in the Sonoff Wall-Touch-switch and it was easy to write a Arduino sketch to it with an FTDI programmer (FTDI prg. is only for the first time needed, after that you can update the sketch OTA).

The Board has only ~14mmx14mm - so it is possible to shrink "Wemos D1 mini" based projects.
Here are a picture to see the Wemos size vs. PSF-A85 (red square):

@NeverDie

It has also 16M bytes flash instead of 4M bytes and a CP2104 USB-TO-UART IC which is new, there is also a external antenna connector available.

Here are the product webpages if anyone is interested:

WemosD1 mini Pro: https://www.wemos.cc/product/d1-mini-pro.html
Wemos D1 mini: https://www.wemos.cc/product/d1-mini.html

The Wemos D1 mini Pro is slightly more expensive than the Wemos D1 mini

@dynamite Haha, especially for the price ;-)

@Nca78 : Decide for yourself ;-)

It is the "Bauhaus" Chess printed with the MonoPriceSelectMini.

Hi guys, I have bought the MPselect mini (320 EUR with shipping and customs to germany) and I'm very happy with it. It is even easier to handle this printer as my Arduino Materia printer and the prints are really good - the printer has a heated bed which is fantastic in this price class. The hot-end temp and bed temp are really stable (+-1°C)
The printer works fine with PLA - I don't know if ABS will work also fine, because I don't have it and so far I know you must disable the hot-end fan to get good results with ABS. My printer has the newest firmware on board which activate the printers WiFi functionality. I can post pictures from prints if needed.

here are a good review on youtube: https://www.youtube.com/watch?v=cSZrqgLj3ag

I use personally different types of mics. Wireless mic, my mobile phone (there is a extra android app availabe "VoxWav") and also a smartwatch (Omate). I have no experience with an microphone array but some user using a boundary mic. Here are a interested post from our forum about the Echo.

@NeverDie said:

I have an Amazon Echo that I like a lot, although I'm vastly under-utilizing it. Is Voice Commando as good as it is at understanding speech? If you mated your IR blasting orb to Amazon echo, I'm sure you'd find a large, receptive audience.

Thanks and yes VoxCommando has a lot of more advantages as the Amazon Echo but it is hard for me to list it all here. I'm sure the Amazon Echo has also its authority, but I don't really know how the Amazon Echo works. VoxCommando do not need a internet connection to communicate to a device and for me it is important to know that my spoken commands will not send over the net to an cloud server. You can use any kind of prefix to start VoxCommando to listening for a command if you don't like "Alexa" ;-)
You can try VoxCommando, because it has a full working trial version http://voxcommando.com/home/downloads/

PS: VoxCommando has also a python API to communicate to mysensors device

Haha, good question and here is the answer:
We have created a IR/RF Blaster ;-)
The video and description show you not the newest version, but it give you an idea of it.

I was inspired by mysensors member "blacey" - https://forum.mysensors.org/topic/1402/ir-blaster-progress
because he never finished his project ;-)

I have bought all my Wemos D1 (30 pcs) from the original seller to get sure they work and they do.

Here are also some similar power supply and they ship really fast

Maybe this will help:

Maybe you can use the parking sensor example :-)
