The problem
Two years ago, I bought some Melnor Bluetooth devices for watering my garden. They worked very well until last year with the Home Assistant Melnor integration.
Summer is coming soon, and I want to put my automatic watering devices back into service. And surprise! It seems that my devices are no longer being recognized properly since the latest updates to Home Assistant.
These devices cost more than $200, and they are essential for managing my automatic watering system.
Some information is still being reported correctly, such as the battery level and the programming timers, but I no longer receive any status feedback from the valves or from the device overall.
battery is OK
BT connection is OK
SO PLEASE HELP AND UPDATE THE MELNOR BLUETOOTH INTEGRATION
