Unknown manufacturer is not OK… btw even your devices are new, battery might be KO…
I would suggest to take a look - Updating from 4.2 to 5.0 – Homey Support and here - Fixing disconnected Zigbee devices (without having to modify all flows) (workaround but it will not fix it permanently) or “Simply” Reset your ZigBee network - it will remove all devices, add them back , fix all the flows…
Please note even you have issues with Aqara devices, it’s rather Homey problem ;-(
