Thanks to the great open-source project Matterbridge, you can integrate your Shelly modules (Gen 1, 2, 3, 4, BLU…) directly into Gladys, locally, without the cloud.
100% local control
No need for the Shelly app
Simple and quick integration
A huge thanks to @Terdious who wrote a complete tutorial explaining everything 
Feel free to ask if you have any questions 
Great work on Gladys at the moment.
Thanks @McFlyPartages, that’s great!
I know you have Shelly equipment at home, I’d appreciate your feedback
This opens up many possibilities, whether in indoor home automation (Shelly behind switches for renovations) or for solar (Shelly Plug or Shelly Pro) 
I have very little time to tinker at the moment. But I really want to move my home automation over to Gladys, which I think is more transparent.
But it takes time.
In any case I’m following it closely and it’s progressing really fast.
With the Matter integration and the major work by Matterbridge and its plugins, Gladys really has new cards
Totally!
Also, the Matterbridge plugin system is really well designed and very simple.
For someone who has a « quirky » integration and wants to tinker with a plugin for their home, it can be a great option.
I might do a live coding session on the topic if people are interested 
While I’m at it, Matterbridge has a Home Assistant plugin so if you want to use Gladys but have a Home Assistant behind it as a « backend » for integrations, that’s perfectly possible!
Not having the time anymore, I realize that Home Assistant requires time just to maintain the solution. And depending on updates, features (non-core to HA) no longer work without intervention on my part. So I’m thinking about what I want and no longer want. The advantage is that I only have Zigbee, Shelly (MQTT) and a few Tuya devices. So Gladys shouldn’t give me too much trouble.
As usual (Jeedom to Domoticz to HA), you have to break away from the logic of what you know to grasp the new logic.
