How to steer an motor?

---

Hey there, i want to steer an 12v Motor per rules like “if it’s 5 ‘clock then open the door and if it’ s 10 o clock then close the door”

Can anybody tell me how i have to connect and steer the Motor in pimatic? Is there already anywhere an plugin?

Till soon

What kind of engine do you want to control. Something similar to a windshield wiper motor?

In this case, you can use a non-potential multi-channel relay. Sonoff’s 4CH Pro (Or a little cheaper here.) with Tasmota firmware would be very suitable. You could then set up this 4CH as a shutter.

Another possibility would be the use of such a relay, without Tasmota. This would have to be controlled via GPIOs, e.g. from Rasperry. For this case the Homeduino-Plugin would be useful to control the GPIOs.
About rules you can prevent a simultaneous switching.

Or rather a stepper motor? In that case, I also found something at Tasmota.

Devices with Tasmota firmware can be communicated with via MQTT-Plugin.

Otherwise, no plugin for an engine is needed.

You are welcome to ask again when you know which variant you want to go.

Thanks for your answer

Once it was for the chicken door @home from a friend, but he bought niw a “chicken friend” @amazon.

But the project is interesting for me, so i want to steer an windshield Motor @home for testing.

So i need:
windshield Motor
Raspberry
Sonoff 4channel switch?

Do i need any relay or something like a motor driver?

So much thanks for your Support

Can you help me @Thrusty ?☺️

@dodo88
A link to the “chicken friend” @amazon would have been quite nice.
But I don’t know what exactly you want to know.
Such a motor must be switched in any case with one or two relays. One relay is enough if the relay has two switching contacts with NO and NC. If your relay has only one contact, then you need two relays.

Here is an example:

Here you can find various connection diagrams for a pole changing circuit.

The sonoff 4ch switches at the relay 230V!!!
Therefore, sonoff 4ch definitely does not work, it must be in this case mandatory sonoff 4ch pro, because this switches potential free.

For this variant you need:
Raspberry with pimatic and mosquitto (mqtt)
mqtt-plugin
DC motor
sonoff 4ch pro flashed with tasmota

The advantage is that the communication runs over the Wifi and no cable connection between Raspberry and sonoff/tasmota is necessary.

As I wrote before you can also use a double relay board to the GPIO of the Raspberry.

For this other variant you need:
Raspberry with pimatic
homeduino-plugin
DC motor
double relay board like this

The communication runs via the cable between Raspberry and double relay board is necessary.
The advantage is that this variant is significantly cheaper.

Okay, for Variant 2 with the relays, i have relay 1 with NC=+ and NO=- and relay 2 with NC=- and NO=+ and steer it in pimatic with “if taster1 is present, then switch relay 1 and 2”? Or how can i switch the direction of the Motor with only 2 telay? In my mind i need 1 relay, who steer the Power to relay 2 and 3, and 2 and 3 are connected like above? And only if the relay 2&3 are finished with switching, relay1 give the Power for xx seconds. Is this right?

Is there anywhere a tutorial how i can build the Sonoff in pimatic?

Nice greets

I had already written to you that two relays are sufficient. I had also sent you a link where many variants are described to the pole reversal. Among many others also the two relay variant.

E.g. this variant is from the side. A short circuit is not possible.

The buttons “S1” and “S2” are symbolic for the GPIOs of the Raspberry.
The circuit would look a little different on the relay side.
With the relay board I sent you a link too, this version would work fine.
How to connect such a relay board you can also find on the Internet. For example, on this page is some explained.
It would be nice if you read the links that I send you also times.

Regarding your question “Is there anywhere a tutorial how i can build the Sonoff in pimatic?” Much sorry, but now I’m starting to feel screwed. After I had entered “sonoff pimatic” on Google, the first result after the advertising was this.

In my opinion the best solution is to flash Sonoff with tasmota and then communicate with the things via mqtt. Sure you have to deal with it first, but once you understand the principle, then there is nothing better. I mean. At least when it comes to wireless. Only for this you need a mosquitto server in addition to pimatic. They can run side by side, on the Raspberry. But even that is not witchcraft. There are plenty of instructions on the net, in all languages.

Okay many many thanks for your help. Sorry for feeling screwed, i’m very unsure in this Things and didn’t search specially for this in Google, i was hope to get the perfect answer for my personally project, i’m sorry.
I will buy soon an sonoff and will try this if i find time for this.

You also need 2 limit switches (NC) if you want to stop the motor, or the motor will spin forever till you switch it off. If its a gate or something like this, it might break something…
With limit switches a single channel (relay with changeover contact) is enough (+ the 2 relays).

@Michael-Rudek
In principle, you’re right, but you can also solve this with rules. That is, you control it with times. Then you can get by without limit switches.
If you use an ESP with tasmota, you can enter the times directly as rules in the device.
If you assemble the whole thing via GPIOs and wired up, the rules or the rules in connection with variables in pimatic work excellently.

@thrusty The Problem is that you can trigger this rule as often as you want. Limit switches are a Safe solution. If it is only a tiny motor, not really a problem. But if it is something powerful you will break something or even start a fire…
