Is it possible implement bridge service?

[faronov]

Is it possible to implement bridge service and add devices to this bridge later as it implemented in Aqara Hub I think esp32 will be powerful enough to serve multiple service and characteristics but how bridge implementation must look like?

[d4rkmen]

Bridge is very easy from the HAP side. First accessory object (AID=1) is category BRIDGE, the rest (AID 2..100) are the bridged acessories. But for convinient work there should be identifiers cache implemented (same bridged devices should have same aid/iid every time)

I tried to add a bridge and statically add a few accessories but failed. Can anyone give an example code for how to make accessories?

[d4rkmen]

Just make sure every accessory uses its own iid numbers (accessory info service should be always iid=1 and so on)

You can take a look at my example https://github.com/nonameplum/esp-homekit-demo/blob/60437fa101ca7eabd1faf6cdd29b360c599ebe3e/examples/garage/garage.c#L344

Garage is the "main"/bridge device. Light switch is another accessory.

[d4rkmen]

You need to change code this way: accessory id=1 category=bridge services=accinfo id=2 garage id=3 lightbulb

[nonameplum]

@d4rkmen what is the advantage of having id=1 bridge and then:

id=2 garage
id=3 lightbulb

Instead of:

id=1 garage (becomes automatically a bridge)
id=2 lightbulb

?

[d4rkmen]

@nonameplum well, you told it does not work with your sample. SO i thought may be thats the point. I never tried myself to make bridges with first accessory != bridge. If this works - why not.

[nonameplum]

I don't see that I told anything about that it doesn't work for me 🙂 anyway home app automatically consider the first accessory as a bridge. Not sure though if making explicit one gives some additional benefits. I didn't try it yet.

[RavenSystem]

If you declare more than 4 accessories, you must use an explicit bridge.

Is there any way to i start on the bridge some web server or through some protocol to work with Homekit to get temperature values on the bridge.

[nonameplum]

If you just add another accessory (HOMEKIT_ACCESSORY) homekit_accessory_category_thermostat won't it work for you? https://github.com/maximkulkin/esp-homekit-demo/blob/master/examples/temperature_sensor/temperature_sensor.c

[Kristian8606]

Sorry for my bad English I obviously didn't ask my question correctly. I would like to send temperature values ​​to my bridge. in this way I will build wireless battery temperature sensors.

Can anyone give me an example of a udp client
