I am using a Wemos D1 as 8266_gateway with a DHT22 attached.
Debug output reports some DHT read errors but from time to time temperature and humidity values are fine.
I used the DHT22 sample code but the device ingnores the "sleep" command.
Node woke-up, reason/IRQ=-2 (-2=not possible, -1=timer, >=0 IRQ)
Is it because a gateway cannot "sleep" ?

connected with HomeWIFI, channel 6
