@joaomf @gusthepenguin for the 2 interruptores e 1 tomada da zemismart please use the modified Muxa's driver code :
https://raw.githubusercontent.com/kkossev/hubitat-muxa-fork/master/drivers/zemismart-zigbee-multigang-switch.groovy
It turned out that these new devices require a special initialization sequence to be sent during the Zigbee pairing process in order to be able to control the 3 child devices independantly.
After updating the driver, please re-pair the device again to Hubitat zigbee network. You don't need to delete it, just go to Devices->AddDevice->Zigbee->Start Zigbee Pairing and pair the device again. After this, you should be able to control the child devices independantly.
SaudaƧƵes!
Update May 2024 : this driver is now available for installation and update from HPM.
