Hi Guys,
Hopefully someone can help with a small problem I’m having. I successfully integrated the Gateway and some PIRs and window switches, all was working till I went to bed, the next day all of my sensors have disappeared 
The only thing in HA is the gateway light, which I can control very happily. Rebooting did not bring them back, re-powering the gateway did not bring them back either. So I’m looking for anyway to get them integrated back into HA. The Xiaomi app can still see them all, any ideas? Maybe I should remove them from the app and reinstall?
