@jpilarski take a look at the I2C hub from Seeed; only problem is how many milliamps your I2C sensors need. My multichannel gas sensor (from Seeed) cannot run on the bus while the BME280 is on at the same time. btw addresses are configured properly.

@calin People who use the M5Stack might be interested in how to avoid breadboards and soldering, and those who use Grove certainly are.

Hi,
Just as an info:
I was wondering if there is a thing like a Grove Shield for the M5Stack. Now, the Grove shields do more, but for running in I2C mode Seeed Studio has the "I2C Hub". Cool thing for connecting 3 devices to the M5.

@pépémax ESP.restart();

found it - it's a Seeed Studio Wrapper

@sunwukong Hey, where did you get the enclosure for the grove sensor? - I've been looking for something like this.

I can power it through my mobile phone charger or a battery pack, just using a tiny USB3 Adapter; and I can power it off my solar panel. I just like the idea of having a web server (or whatever else I made ...) that I can plug into an AC socket.

That thing should have a CE certification, I think ...

I would like to be able to buy a bottom element that is itself a power plug with a transformer. That way I could just plug the Stack into a wall socket and have a 24h-machine. And since I am in Europe, I would prefer to have the European model first :-)

That would also help put the Stack in a nice 45° angle while I am developing (while having the Stack connected to my PC by USB)
