I know, but in this case we are talking about 230 relays controlled for home automation.
Of course, for a gadget running on battery we will not make the connection in wifi ...

Hmm, unless I am mistaken at the outset, we are talking about a hay distributor for horses in a meadow, a priori (I may be wrong) without 220V.

The WIFI arrived later in the discussion thread as a possibility of communication.

Pending the return of the person who made the request, the discussion had deviated from the subject ...
But after yes, for the original question the 433Mhz can be a solution ... except that to control the gadget from the web from the outside it will be necessary to go through a gateway, maybe even a small home automation server or a gadget having approximately the same function ... For having followed several projects launched by the author of the request, in my opinion it greatly exceeds it ... therefore the wifi, despite the power supply constraints (not insurmountable ...) that remains of "plug and play" much more accessible than the RF solutions that I have seen.

Hello,
I see that for sonoff and shelly, the best part of the circuit is the EPS8266. It also has its arduino version https://f-leb.developpez.com/tutoriels/ ... 6/debuter/, more flexible because the first are all in one intended for the 230 V network.

They can therefore all be supplied with 3.3 V, this is what to choose for the battery in isolated site.
Otherwise the remote control 433 mhz without wifi is also done https://fr.aliexpress.com/item/33023724263.html, to avoid in town because risk of triggering by a neighboring remote control, number of different codings limited.

Hello everybody

I reframe the debate a little because it turns to exchange between specialists and moves away from the initial subject: the IoT in general.

The purpose, in my case, is actually to be able to control a hay distributor remotely, but it would be interesting to study the subject to find out the possible solutions according to the intended applications and the environments.

To synthesize your answers, I already see 2 areas that require different solutions and materials:

1- Either there is a local and close WiFi terminal, therefore a priori with 220 volts current, and in this case the network is already in place and there are many possible solutions by connecting to this network which allows a unlimited distance management via internet. The presence of 220 volts nearby also allows you to choose certain equipment operating on the mains.

2- Either there is no existing Wi-Fi network, or 220 V current, in which case other local and autonomous solutions must be found: GSM chips, dedicated mobile phone, other SigFox type network, and power supply with battery and / or solar panel.
(In this case, it is this configuration which concerns the hay distributor project).

(3) - There is also the intermediate solution of the local bluetooth network, but which remains a proximity solution in the sense that management can only be done within a radius of a few tens of meters around the connected object. This solution is the one adopted for certain watering programmers in order to manage the programmer from his house using the bluetooth of his mobile phone. It's interesting but it's still very local.

Note also that the needs of the project go beyond the ON / OFF solution because it is necessary to be able to indicate timetables, with a possible return of the connected object to say that everything is ok.

As soon as I have time, I will make a synthetic table of these contexts, because all relate to the IoT but the uses are different and the technologies and possible materials are also very different.

(NB: this project was submitted to undergraduate level students. Unfortunately, the Covid19 crisis stopped everything and postponed everything until next year. In principle, we will resume the project at the start of the next school year. The current debate is already making it possible to plan the subject, and I will tell you what will emerge from the students' first research work).

I feared it without having expressed it, but it will do as for the electric assistance of your horse-drawn car ... although we give you all the solutions here you will never stick your fingers out to do anything and it will take someone else is leading the project for you.
No need to go further, the topic will turn to the wind.

It is the professional turnkey solution https://www.objetconnecte.com/tout-savoir-sur-sigfox/ and here it is a question of ordering a simple solenoid valve ...
Unless you plan to evolve the system to remote control the robot arm which will take the hay bale on the haystack to distribute it at the desired time, so you no longer have to move?

If you are lucky enough to have patronage at your disposal, why not : Lol:

... not as windy as that, it allowed me (and others too I think) to know some nice stuff (Shelly ...)
Arduino, iot, raspberry and the like, for someone who has no concept in electronics or coding, contrary to what we say, it's anything but simple. There are excellent tutorials but you have to be a hacker to make it a hobby and spend tons of hours learning.
A very good pedago for me is Thonain https://www.youtube.com/playlist?list=P ... TZpg3yMU5f
He is a beginner himself and starts from scratch.

I do not understand this aggressiveness without reason and even rude!

If this subject does not suit you, you come out, it's as simple as that.
The derogatory and vulgar remarks have no meaning or interest, and I wonder besides what is their purpose ...

For now, we are siding the subject and obviously things are not as simple as what you say, especially since there are many other aspects to the project and already several possible solutions. I also think that many of us are discovering the field of IoT, existing applications and hardware.
If I have to tell you that we start from scratch, I tell you without any shame: YES we start from zero and we discover from the comments, examples and links given in the discussion. We will also probably make mistakes.

You should know that I am not the only one working on this project: there are the professors of the technical higher education courses interested (mechanics, electronics, etc.), some professional friends from the equestrian sector who give feedback from the trials in situation, a A&M engineer who gives us some details when the technique is too complex, etc.
Everyone has their own area of ​​expertise, and each contributes to the building!

Later at the start of the school year, there will be students who will have to dig into the various stages of the project (electronics, mechanics, IT, ergonomics, etc.) and propose solutions. Generally, there are original ideas and solutions that we haven't thought of.

It does not seem to please you that students (course, boe) and students bac + 2, + 3, or +5 work on such projects.

For me, this is important and it is a choice, which I repeat every year at the request of the professors who find that the concrete subjects carried by one or more professionals in the sector bring much more to the students, and especially since this type of project allows collaboration between various establishments of different technical training.

It also makes it possible to get out of conventional work patterns that are much less pleasant, often stressful, where rivalry, competition and power relations are required. With the students there is an interesting pedagogical approach for the team, the project, and the professional partners often more inclined to give their time or offer materials and the provision of tools and workshops to produce a piece. complex or program a device.

For the electric horse-drawn carriage many professional companies offered us expensive equipment (batteries, controllers, programmable logic controller, sensors, etc.), then some even offered internships to students.
You see, this type of project is not just the development of a technical hack; there is also an equally important and fascinating human and educational aspect.

The horse-drawn car with electric assistance project was an indisputable success: the open debate on econology has given rise to numerous proposals and made it possible to plan the tracks well. The students used it for their work. We tested several of the technical solutions from econology to finally get closer to a solution that worked well.

Many national journals have made articles on this project and several films have been made, notably on equidia .... and the student engineer who made the last adjustments and improvements on the electric carriage was recruited by the CEO of a company that read an article on the project in a newspaper (La Provence) and found the work interesting ... and hired the student.

Note also that the project served as a working support for students of the CAP level in ironwork ... up to a student engineer of Arts and Crafts, passing by students of mechanical IUT and electronic BTS, and the 'ENTE (National School of Equipment Technicians).
This vertical collaboration was, in my opinion, much more interesting and more remarkable than the final technical result.
Imagine a working group that brings together around the same project and in the same workshop students in cap, iut, bts, and engineering students.

In the end, a functional prototype of a Horse-drawn Car with Electric Assistance was produced thanks to the work of each level of these students, and this prototype received a national innovation prize from the French Institute of Horse and Riding. (IFCE) with the team's invitation to the award ceremony in Paris in the barracks of the Garde Républicaine des Célestins.

So it was a great success, both technical and human.
Maybe this new project will have the same success, with or without fingers in the ... or a mix of wind! ...
