4CHR3 cannot turn on multiple channels.
**What issue do you have? Please be as thorough and explicit as possible.**
I have a 4CHR3 installed and working perfect through the eweLink app. All channels can be turned on and off independently without issues. However, I noticed that I cannot have more than 1 channel turned on through Homebridge. If I turn CH1 on then turn CH2 on, then it will turn off CH1. This applies to every channel, turning on a single channel will turn off all other active channels. The master switch CH0 still functions correctly. Homekit and HOOBS will still show the switches as on even though they're off.

Example:
1. Toggle CH1 (CH1 turns on)
2. Toggle CH2 (CH2 turns on and CH1 turns off)(Homekit and HOOBS still shows CH1 as on)
3. Toggle CH1 (CH2 turns off)(Homekit and HOOBS shows CH1 off but CH2 still on)
4. Toggle CH2 (Nothing happens)(Homekit and HOOBS now shows CH2 off)

The log below shows the steps I mentioned in the example above right after a fresh restart of HOOBS. It seems to be turning off other switches when I turn on one of them and turning everything off when 1 is turned off.
...

**Details of your setup.**
Do you use Homebridge or HOOBS?
HOOBS with a TadoAC plugin as the only other plugin.
...

Which version of Homebridge/HOOBS do you have?
3.2.9
...

Which version of this plugin (homebridge-ewelink) do you have?
3.10.0 but the issue has been there before I updated from 3.5

**Please paste any relevant logs below. It helps if you can turn `debug` and `debugReqRes` in the package settings for more thorough logging.**
> If you are posting an error then it is helpful for me to also see the previous few lines as this can show the cause of the error.
