I updated the deconz add on to the latest version 5.3.6 and following I updated the ConbeeII device firmware to the the version of 22-5-2020 0x26580700 .
HA worked well before the deconz updating. After the deconz updating, all the HA system seems to run slowly and in particular the interactions with devices associated to the conbeeII…Every 15 sec or after the HMI interaction with some deconz device (i.e. light,sensors…) the deconz device icons presented in the lovelace page went in disabled mode(light grey)… After 30 sec… they reappeared in normal mode.
Following the log extract of the deconz addon
