@laszlocsaba imgObj.onclick = ()=> { this.sendSocketNotification("CLICKED", somePayload) } I think you might have some confusing with using this. If you are using ES6 style arrow function, you can easily bind.

@laszlocsaba very interesting! The module should be expanded for all other “Shelly” sensors (Relays, Sensor and Plug and play…). Are you planning to expand the module? Thanks.
