Support for Shelly Blu Gateway #395

Closed Spartacus68 closed 6 months ago

Spartacus68 commented 6 months ago

Is your feature request related to a problem? Please describe.

no issue **Describe the solution you'd like** I would like to add the new Shelly Blu H&T once it is available. In oder to bind thm into the WLAN I would like to use the Blu Gateway **Additional context** The stick is ordered and I can provide you details if you like.

What will be the profit from adding support for a device that can not be controlled and which does not have any sensors?

Spartacus68 commented 6 months ago

Hi,

I am not really sure, but I guess that the gateway is necessary to add the blu devices to WLAN. Maybe it is transparent and there is a differnt way to connect Shelly BLU H&T to Homeassistant. I woll let you know. amazon will deliveer today the Gateway but for now I do not have any bluetooth device.

You can use BTHome integration to configure BLU HT/Motion/DW with HA. BLU gateway is not necessary.

Spartacus68 commented 6 months ago

Hm, I don´t think so. The HA server is far away from any Bluetooth device (more than 50m) . There must be a GW between WLAN and BT in the near environment of the H&T Blu to connect to HA

Every Shelly Gen2+ (non battery-powered) device can work as BT proxy for HA.

Spartacus68 commented 6 months ago

yes I know, but in the summer house there is no shelly gen2+ therefore I planned the GW in a USB Charger!

The device is online. Here is a screenshot from mqtt Explorer image

The new BLU H&T are not yet available.

Nothing interesting here

The new BLU H&T are not yet available.

ok, it seems to be that you have it! But they are not avaiable in the shelly store at the moment.

And, the question is, how they connect to BTHome, I use all my shellies Gen2. with mqtt and I do not have a clue how theycan connect without a shelly Gen2 in the near environment. Can BTHome connect to the H&T over the Gen2 Shellies WLAN? And how does the Gateway can connect to the MQTT-Server if it isn´t supported by your integration? Sorry for asking stupid questions but I belive that the Blu Gw must be attached via mqtt to HA.

Spartacus,

To use BTHome integration, you must have at least one BT proxy configured for HA. It makes no difference whether it is Shelly gen2+ device or ESP32 with ESPHome. You can use Shelly BLU Gateway for this purpose, but the device must be configured via Shelly integration. MQTT does not (and probably will not) support BT event forwarding to HA BT integration.

Spartacus68 commented 6 months ago

ok, then I'll send the Blu Gateway back and install a Gen2+ in my garden shed! But just to avoid any misunderstandings, the Gen2+ will support BT forwarding in an MQTT integration, right?

bieniu commented 6 months ago

No, you need to configure the device with the core Shelly integration to make it a BT proxy. MQTT doesn't support BT event forwarding.

Spartacus68 commented 6 months ago

Is BT forwarding planned? If not, what's the advantage of MQTT integration over Shelly integration if not all features are supported? Sorry, I don't want to start a fundamental discussion, I just want to understand.

I decided to use mqtt because I also connected Zigbee devices via mqtt, because the Zigbee build-in integration does not support all devices.

bieniu commented 6 months ago

Is BT forwarding planned?

No because it is not possible to implement this without external module that parse BT events.

If not, what's the advantage of MQTT integration over Shelly integration if not all features are supported?

The main advantage of MQTT is that devices can be in a completely isolated subnet or in the remote location, in the case of core integration this is practically impossible or very difficult. You, as a user, must decide which integration you want to use and why. There is no discussion here about what is better and what is worse. These two ways of integration are simply different.

Spartacus68 commented 6 months ago

Ah ok, I never thought about this because I am using HA in dedicated subnet :-).

It's a pity that this is not possible via mqtt! Then, I think, it makes sense to use the BT Gateway with the Shelly integration to have it exclusively for BT purposes and continue to run the Gen2+ via mqtt. Thanks, that was enlightening and thanks for the discussion.
