Definitely, you really want to move a debate on a technical subject (which one does not control) towards a conflicting debate. I still do not understand the reasons for your harsh comments.

You gave a solution, which concerns a stage, and I thank you for it. There are others and for the moment we are learning about each solution to know the level of difficulty, the cost and the possibilities of evolution compared to the project.

However, initially the subject is: "Connected objects, IoT, IoT". (I simply gave, in brackets, a very specific application on which we are working and which uses this technology, which prompted our questions and our research. That's all).

Let's stop these aggressive comments which have no reason or interest. If you want me to repeat to you that we are not competent in the field of Connected Objects, I tell you and repeat: we are not competent in the field of Connected Objects. We learn and we discover this field as and when the information received. Point. What more can I tell you?

Your comments seem more like ad hominem attacks than technical criticism.
Let us puncture the abscess in order to avoid these recurring comments without interest, and discuss the technical aspects, even if certain technical solutions are adaptable to certain applications and not to others.

Good, since it takes at least 12V for the feeder motor, a solar panel + a regulator and a battery are enough, all connected to a 12 V programmer. No need for wifi, bluetooth, arduino or other gas factories .

200W solar panels with regulator 266.09 euros:

We can even think of a motion detection trigger, 3.87 euros:

12V timer, 7.21 euros:
https://fr.aliexpress.com/item/32636597 ... web201603_

Battery 120 euros:
https://www.batteryset.com/batteries-a- ... zpEALw_wcB

It remains only to connect a window lifter or wiper motor, a contact switch * and voila. I admit that this is what I would do, always going to the simplest in my way of tinkering.
Anyway, smartphone, wifi, arduino or others, it will always be necessary to move to recharge the feeder ... : Cheesy:

200W on a day (which does not make 200W x 24h certainly, but it remains colossal) to power a motor of 2-5W for 5-10s?

A 90Ah battery?

It seems to me that it is necessary to review the sizing! : Cheesy:

So much the better if you need less, it will be cheaper ... That said, I do not think that a window regulator or wiper motor consumes only 2-5W.

Yes I have enlarged the line a little, it is rather around 35W, so 12V 3A.

3A for 10s, powered by a battery that can provide 90A for 1h, we see the difference in size, there is indeed room to find smaller and cheaper (it's always more fun in this sense!)

Ditto for the solar panel, 200W displayed, between the sunshine and the real output, we must be able to actually store 200Wh each day, while the motor requires 36W for 10s = 0.1Wh

My figures are shady, but we see that we must be able to divide by 100 without having a problem, hence my remark on sizing, but hey, we are more there in a counter discussion than in a real technical discussion. ..

50W solar panel with controller, 26,80 euros

12V / 18A battery, 69.74 euros:
https://www.manomano.fr/p/batterie-moto ... h-10054470

Motion detection trigger, 3.87 euros:

12V timer, 7.21 euros:

Contact switch 12.97 euros:
https://www.manomano.fr/p/interrupteur- ... ge-5928906

We are at 116,72 euros, without the motion detector and without the motor, to buy in a breakage at low prices.
Long live simplicity.

Uh ... that is to say that everything you describe ... it's already developed locally, and on batteries! : Cheesy: That said, a small PV panel would allow more autonomy.
A priori no need for a 12-volt battery, nor a couple of wiper motors because the system just unlocks successive latches to release meals at the scheduled times.

On the other hand, your link to the programmers on Aliexpress is interesting but you have to see if we can make them work on low continuous voltage (they are in 220 v).
For the motion detector, this is not suitable because equines will systematically trigger the system ... it may even become a Pavlovian reflex: "I bring my nostrils close = I have to eat"!)

The idea is now to be able to intervene remotely on the current system operating locally, and to have, if possible, a return of the good functioning, from where the discussion on the Connected Objects. (Note that indeed, local operation, namely prior loading and programming of ration times already addresses a good part of the problem. Making the system a "Connected Object" would allow remote intervention to review or verify the programming. , but above all to allow the manager (manager, team manager) to check that everything is ok in the evening when everyone is gone.

Currently, the tested system works in the following way: the successive rations are loaded during the day (generally in the evening) (up to 8) to be given in portions in the morning. (For equines several small meals spread throughout the day are preferable to 2 or 3 large meals) <;
We program the hours and it's over (the schedules can only be programmed once unless there is a change) ...

But when you have equines parked 500 m from the center, and you don't know if the groom (or the trainee - there are many in the equestrian sector !!!) prepared the meals, and if she / he has set the right times (especially if there have been last minute changes), you must go see on the spot (or call the groom or the trainee), while a connection to the system via your smartphone or tablet allows you to do this in seconds. This does not prevent it will still go to see on the spot if everything is ok and make a cuckoo and a gratouille to the dada so that they do not get depressed, especially when they are retired equines ...

To give you an interesting example: we have a request from the manager of a large equestrian structure (around 300 equines parked in several parks on several tens of hectares. Currently, there are racks in which he deposit a large round bale of 300 kg of hay, but some horses do not know how to regulate and eat all day to get sick, some make twists.

Distributing the rations with the right quantities at the right times is already good. If in addition the manager can check that everything is ok from his comfortable living room without stepping outside ... it's better, even if, they say, "the best and the enemy of the good"!

So plan a camera in addition ... Personally, I find all this binz if not useless, at least superfluous.

Your link to solar panels is delivery via DHL, and if delivery via DHL = customs fees. It's already about € 20 commission by DHL, plus customs fees .....
