Wemos d1 Mini how to start?

---

Hello, i will start with building WiFi Sensor but don’t know where to start?

Is it possible to buy a wemos d1 Mini and flash a Sketch on it to send for example Temp directly to pimatic? I like the wemos because of Micro usb its easy to Plug in and flash.

A hint were to start and if it’s possible and with witch Sketch would be awesome.

Thanks in advance.

Did you already found espimatic?

Oh Thanks for that. But is it possible to flash. It easy on a wemos d1 Mini? Did someone succesfully Test it?
Thanks

sure, you can easily install it on a wemos.
i have severeal d1mini here running succesfully with espimatic.
you can flash it like an arduino.
for espimatic you need to use the arduino ide 1.6.5 and the board manager 2.0.0.

here’s my dashboard from the balcony, as you can see there is data from an dht22 provided.

having also 4 relais, an analog sensor as rain detector and an led matrix for showing the actual temperature outside on the balcony.

espimatic is a really nice and easy tool!! i like it

Awesome. Thanks for the fast Replay.

But how did you manage to get Micro USB to 3.3v i only can find 5v Micro Power usb

the wemos has a stepdown converter on board so no need to worry!
you are also having a 5v pin available. that’s very useful for some sensors.
but the input on the gpio is still 3v3!!

See also ESPEasy. According to me, the best universal software for ESP8266.

EDIT: With this plugin for Pimatic API, even better.
