Fix bug in local response from AltoBeam GTWS78

[AutoHome2022]

Dear Community, Exellent work by the SonoffLAN team I must mention.

I am heavily invested in use of Ewelink and Sonnoff range of products.

I have been having issues with my 1 gang wall switch labelled GTWS78 by AltoBeam Firmware: 1.4.1. Unfortunately, I have several of these switches becuase I used them in a whole house automation project. I have just upgraded my SonoffLAN version to 3.5.1

Please see attached debug snapshots (look at the time Stamps). It takes in some cases up to 30 seconds before the Switch State is correctly updated in Home Assistant. However, actual action of switching ON or OFF happens less than a second. I have reviewed #issue 928 looks like it does not apply to me. Please note this behaviour only happens in LAN mode ONLY. Auto or Cloud Mode works fine.

All other TX3C wall switches by SONOFF work flawlessly in LAN mode without this annoying behaviour.

I will really appreciate any assistance becuase changing all the switches is really not an option plus I cant even find 15A wall switch official sonoff.

I need your device "devicekey". With it I can decode response and check what is wrong. You can find device key here: /config/.storage/sonoff/...json

Awesome Thanks for getting back to me. As I have several of them. and it appears they all have different 'devicekey' I have picked 2 of them. Please find below. do let me know if you require the rest.

"name": "##### Heater", "deviceid": "100119e52a", "devicekey": "26e6e7ab-7305-48be-b2ef-2fc08ae64083"

Appologies. Please find below as requested "devicekey": "9b0810bc-557a-406c-8266-614767890531"

Wow super awesome. thanks a lot. It appears this patch 'just' missed the v3.5.3 relsease'. Honestly I actually don't know use the raw source code or the master version in HACS.

Will snoop around for how to do this otherwise I will just wait till the next realease with the joy this matter will be laid to rest now. super super happy

Mega Thanks

Ok a little bit of feedback 

Unfortunately the controls are still seriously lagging. I have been able to update to v3.5.3. Also I thought I have used the 'master' version as well. Rebooted. Home assistant still same. if I use cloud or auto everything is fine. 

 Thanks again
