#Solution for light switch

Hello,
I need to switch a light where I can not use a classic wired switch. But I still want to use a Hardware-switch to turn on/off the light. I thought about the powerless switches but they are really overpriced. And since I will already use HA for the shutter, I thought its cheaper to just use shelly plus 1PM as a solution to my lightning problem.
1 shelly as actor and 2 shelly as sender mounted behind Hardware-Switches.
Is that possible? Can I controll the output of one shelly 1pm with another shelly 1pm? So that one shelly only acts as an actor/receiver and works only as a remote relais.
Or do I need a different setup?`

Thanks for your help and input

i think the answer is probably yes but i am not totally sure what your trying to do. can you maybe diagram it

This should explain it a bit more. I want to controll the light with sender 1 and sender 2. To make this happen I thought I can use a shelly for the senders as well as for the actor. while the actor shelly is only taking input from the sender. And the sender is a classic hardware button beside the doors

you could do this, but you could also just put 1 shelly on your light and then put a ble/zigbee button whever you want a switch

#

if you put a shelly somewhere then you will need to power it. so will need cables to it anyway.

what is the current setup? is there a switch at one of the "senders" (and you want to put in a 2nd) or is there a switch near the "actor" (and you want to add 2 new switche)?

#

i think you can do what your trying to but i feel there might be a better way but i am struggling to understand "where you are" and "where you want to be" so i cant suggest much more

The rooms is actually much bigger and i have a few more lights. So at both sender positions is already power and several other wired switches. Just this light is a new one and I don't have a wire to switch it from those positions.

So ble/signer works without power? As long as I can use it together with custom covers, this solution could also be a alternative.

#

Oh that's gen 4.
So I can buy a Shelly gen4 Relais and use any zigbee sender with it

#

you can use any gen stuff as long as it connects to home assistant

#

for a zigbee switch you will need a zigbee receiver though. if you get a ble one then you can use the shelly as a bluetooth gateway

#

wireless buttons dont need power, they have batteries. and with something like ble they will probably last years for something like a switch

#

I just read that gen 4 supports zigbee. That should make the zigbee receiver obsolete. I will read up about that a bit more I guess. Because I also want to controll a few shades later on

#

it supports being a zigbee device, but i dont think it supports it being a gateway. if you want to control zigbee devices with home assistant you will need a gateway/hub of some sort

I have a bunch of shelly in various flavors in boxes all over where I could not do otherwise. They work OK, though have been a tad flakey (I should add that after the last few rounds of firmware upgrades they seem more stable). I also have a bunch of Lutron Caseta, and they are by far my preference. They just work, all the time, every time. The bridge continues to do most functions (that are not tied to HA automations) even if HA is down. And the little "pico" switches mount in a plate that makes them look just like a boxed switch, except you can stick them on tile, brick, etc. without having to drill or cut. The HA integration is seemless as well, plus the Pico's can be used to control non-caseta stuff (like Shelly's, but I have them on garage doors, fans, etc.). The Caseta stuff is not cheep, but it just works, and there is value in that.

your "actor" doesn't have to be a light switch since it will not have any physical lswitch connected to it. it can be any small relay switch. like the shelly 1 mini or 1pm mini if you prefer the shelly route.
the new upcoming shellys are multi protocol, so they will support zigbee as well it seems. they are of course not tested in ha yet, but i assume they should work. as noted earlier here you will need a zigbee orchestrator of some kind to use zigbee. i use a nabu casa skyconnect usb dongle in my ha server. or you can just use wifi. shellys are ok on wifi it seems as they are locally controllable by design (and not through hacks like tuya wifi)
your senders also do not need to be a full light switch, as they have no use for the relay. but they may be the way to go if you want it to be mains powered and hook into any existing physical switch. another route is a zigbee button/switch mounted on the wall anywhere you want. those are battery operated, so no wifi versions of those 😄 that would empty the batteries too quickly...
and the last version is of course to just wire that new lamp directly to mains and use a smart bulb instead of the actor. still with the same options for the switches

since linwood came up with the problem that shellys aren't up 100% of the time I was questining if they are a good solution.
maybe I should look for a kinectic solution. no batterie at all, but also a much higher price and no HA or any smart intergration .. at least from the products I found

#

there are some kinetic zigbee switches? those round hue things?

wraith berry

I only know some products that use the EnOcean standard. Like the relais from eltako.
But thats already 50$ for the relay and probably the same for one switch
