is it possible for one espeasy device to control other espeasy devices

[ufumes]

Hi,
I have multiple espeasy configured devices and i want to be able to switch some of the devices based on the states of one of them, pls is this possible and how can i accomplish it.
Thanks

You can do that using HTTP, MQTT, or UDP. What's your environment first of all.

PS. MQTT is by far the best way in my opinion.

If you have an MQTT broker, or you can install it to anywhere, for example on an OpenWRT router, or a Raspberry PI, then MQTT is a good way. Then ESPEasy devices can be controlled by any other node (either ESPEasy Publish command) or by other mqtt clients.

If that's not what you tought, then:

1. At "Config->Unit number" you can set an ID number to your ESP.
2. At "Controllers" you can select "ESPEasy P2P Networking".
3. "Tools->Advanced->UDP port" you can specify which network port do you want to use.
Then you can control directly any ESPEasy device from another (in the same lan) without knowing it's IP address, simply by using:

SendTo: SendTo <unit>,<command>

Earlier there were also a "Global sync" option, which i shomehow can not find in the latest ESPEasy Mega releases, this was exactly made for exporting variables between ESPEasy nodes.

Take a look at:
https://www.letscontrolit.com/wiki/inde ... GlobalSync

GUI example is not fully correct anymore (fore last picture is changed)
Look for Inter-ESPEasy Network under Tools/Advanced
Fill-in an UDP port and it should (?) work.
Make sure that tasks are uniquely numbered in the group of ESP's.
All tasks will appear in all nodes and kept synchronized by the UDP port.

As far as i can see GlobalSyncv isn't available in the last Mega versions.

It has been moved from advanced settings to a controller. You find it in the drop down.

Thanks for your responses. Am interested in connecting them in the standalone mode + http. I eventually came across the sendtohttp rule which helped me in communicating directly between the espeasy devices without a controller

I hope to explore this option(sendto) too, since keeping track of changing IP address can be worrisome

It has indeed been moved from that plugin-checkmark to a controller (C013 ESPEasy P2P network), since it has essentially the function of a controller.
Its implementation is still a bit 'experimental' (read: it has lots of room for optimization, especially when using lots of nodes)
