Trotzdem lässt sich AC einfacher in den Griff bekommen als DC.

Da hast du wohl recht, wenn ich mich recht entsinne stand dabei, dass der Varistor für den ganzen AC- Bereich verwendbar sei.
Wobei üblicherweise der AC- Bereich ja generell unkritischer ist, da 50x/sec einen Nulldurchgang stattfindet.Das Problem ist, dass es vielen gar nicht bewusst ist, dass es da überhaupt etwas braucht.

I assume that you did connect the reed contact to SW input of Shelly.
It could make sense to simulate the operation by using a casual switch, or just a jumper, instead of the reed contact, in order to see, if that works.
Such you could see if the problem is on Wiring side.
Further you have to check carefully, whether you have to have a positive, or negative polarity connected to SW input.
From here one can see, that Shelly expects to get negative signal connected to SW input:

A last thing is t check the settibg of contact type, as momentary, edge etc.

Das Problem an Varistoren ist, dass man seine Durchbruchspannung erreichen muss, bis er aktiv wird, hat der Verkäufer die Schwelle zu hoch gewählt, nützt er einem nichts.
Ich verwende im AC- Bereich nur R/C- Glieder und im DC-Bereich nur Dioden und bin bis dahin gut gefahren damit.

Hier zwei Beispiele:
MFZ12-230Voder:
MFZ61DX-UC

Die gibt's auch unter Homekit, nur unterscheidet sich das Format bei der Eingabe:

Es ging nur um die Art der Eingabe von Timerwerten unter Homekit.
Zu der Verdrahtung gibts hier im Forum fertige Lösungen.

Wie wäre es mit einem Shelly 1 und einem Hilfsrelais/Hilfsschütz mit einem Umschaltkontakt.
Solange der Shelly Ausgang inaktiv ist wird Pumpe 1 aktiviert, sobald der Shelly Ausgang aktiv ist zieht das Hilsrelais an und Pumpe 2 ist in Betrieb?
So wäre zumeindest sichergestellt, dass immer eine Pumpe aktiviert ist.
Will man noch etwas mehr Sicherheit reinbringen kann man ein Kammrelais mit zwangsgeführten Kontakten verwenden.
Auf jeden Fall darauf achten, dass die Kontakte für die zu schaltende Last ausgelegt sind, um ein langes Leben des Relais/Schützes zu garantieren. -

Johnpsom was only looking for a way to get the light activated, if door is in operation.
The issue with DW modules is the lifetime of included batteries.
A casual garage door is mostly closed, whenever it receives an opening command, it wiill be closed again within minutes.

To be honest, I don't know, I don't have any 4PM or Plus devices, so I can't double check.
-
You could open a ticket at Allterco by hiting on support button on the left menu bar.
If you enter the PM IP adress in browswer followed by /status, you should get a status report of the device, it could be helpful for them to get the report as base for further help.
I assume that you allready tried to set it back to factory default and start over with configuration again? -
Here a link to a sample of a Interface relay. They exist in thousand different versions, also in regard to mounting features.
As the motor is operated with 220V, the relay coil also needs to be suitable for 220V.There is one normally open contact needed, as there will only be switched a few mA's, a contact rating of 2 Amps, would allready be good enough.

If I remember right one of the SW inputs is foreseen to toggle on/off and the second one is foreseen to be used to dim.
Alternatively there exists the one button mode. -
If I remember right, Internet connection will not be used any longer if you switch to MQTT.

Shelly 1.jpgI don't think (as described above).
From my point of view it should be sufficient to use the open command as trigger and then set an off delay of approx. 5 Minutes.
But most probably you would have to add an interposing relay, such that the SW input will have it's own dry contact.
If there exists allready a Shelly which controls the light, it could be an option to think of using a Shelly 1PM which could be used to detect operation of door, in either way and then send an http command to the Shelly which controls the light, once the door is getting an open or closed command.
-
If you open the device GUI by entering the Shelly IP adress in browser --> Internet & Security --> Advanced - Developer Settings --> you can tick the Enable MQTT box.

Theoretically the Shelly could be fed by 220 then, but linking the opening command on terminal 6 to SW of the Shelly might not work, without interposing relay.
There are this 110V on SW terminal, which allow either to lift the voltage up to 220, or lower down to 0, in order to cross the switching threshold of Shellies SW input.Due to that the motor loop would influence the SW input of the Shelly.
-
Did you check the operating voltage of the motor, they are often operated with 24VAC?
-
Ho will the opening/closing be initiated, by linking 7 with 8?
Or just by remote?
