**What issue do you have? Please be as thorough and explicit as possible.**

My L1s worked fine with plugin homebridge-ewelink-sonoff@2.10.2, any newer plugin introduces lagging to L1s:

L1 response time using homebridge-ewelink-sonoff@2.10.2 - Instantaneous, independent of number of times i turn it on/off
L1 response time using homebridge-ewelink@2.25.0 - Instantaneous at first time, adds 1s to any next try. On 5th attempt it´s about 5 to 6 second to turn it on/off.
