use localhost instead of the ip
localhost/light/0?turn=toggle
local.host/light/0?turn=toggle
127.0.0.0/light/0?turn=toggle
127.0.0.1/light/0?turn=toggle
none of these are working. I don't have authorization setup so that's not the issue. Plugging the ip address into my browser (see previous post) works.
on second thought, this seems to not be working. I have the url under SW2 on and SW2 off:
http://192.168.86.31/light/0?turn=toggle
My HA recognizes the SW2 toggle but nothing happens to the light.
But how you should can do this without another service.
Set button type to: one button toggle mode
And use at SW2 local actions with a toggle command
Can you please explain how I would create a toggle command with the SW2 local action?
Nevermind:
192.168.86.31/light/0?turn=on
192.168.86.31/light/0?turn=off
hey all!
I have a three-way circuit with two switches at two different polls. One connects to L and the other connects to O. I have two travelers between them. Would the following wiring work?
Thank you!
EDIT: so I tried the circuit and it doesn't work, but only because the software doesn't support it!
When the left-most light is toggled the SW2 in shelly is toggled on/off; I can see it in home-assistant. But the light does not toggle.
The solution for me was quite easy: I made a rule in home assistant that if SW2 toggles, then toggle the light.
But why should I have to make a work-around in HA? With a product that's already so well built and with customer service that's so amazing (I'm trying to build "brownie points" here), why not have this as a built in button type?
