Anyway, smartphone, wifi, arduino or others, it will always be necessary to move to recharge the feeder ...

Uh ... that is to say that everything you describe ... it's already developed locally, and on batteries!
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
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"!
