Phoscon integration sensors

HI, I have a problem with Xiaomi agara, (temperature, humidity pressure …) Have 3 of the same model, I have managed to install 2 but not the third in Phoscon interface. It is the same device that does not want to install, has changed the battery. I use the same procedure to install, for all 3 devices, but only 2 devices can be installed. The third is found by Phoscon, it says ready unit, but it is not visible in sensors. Only 2 units are visible in sensors. What could be wrong. Have tried to remove the devices from Phoscon, reinstalled, reset Xiaomi devices, but it becomes the same problem, that the third device is not visible in Phoscon sensors.
Grateful for help.

I’ve the same issue with other sensors. Phoscon seems to be quite buggy. Are there any alternatives to deconz?
