Now we have constants like Gree.VALUE.power.on which is equal to 1, but during polling process we are getting parameters in string representations.

For example

client.on('update', (updatedProperties, properties) => {
     ...
     const value = updatedProperties[Gree.PROPERTY.power] === 'on';
     ...
});

For now we need to use on string value.

Do we need to add constants for such values, what do you think?

Hi!

is there a chance to get this adapter running under Windows 10?

Hi!

First, thank you a lot for your work!

So about the issue, the 'update' event is only triggered when I connect but after when I use setProperty or setProperties the event is never triggered (the property is set correctly on my Gree hvac).

But if I use the official app, the event is triggered.

Am I missing something ?

Hi

What do you think about adding noPollingResponse event (or something similar?) which can be emitted in case when HVAC doesn't respond to the polling request?

For example we have polling: true and pollingInterval: 3000.
Using setTimeout with pollingInterval*2 we emit noPollingResponse.

It allows library users to handle case when polling was not successful and mark device as offline (for example).

Any thoughts about this?

I get this error when trying to connect to a gree Hi wall AC.

Hey Igor 👋

I've found that some users are getting Error: error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt error in

I'm not sure why it happens as I don't have any additional data (wrong encryption key? broken data?), but can we somehow handle this? I mean allow developers who uses this library handle such cases somehow. Because it's happening inside the library now.

Hi! I'm trying to connect AC device to local wifi using the command from read me ( echo -n "{"psw": "pass","ssid": "ssid","t": "wlan"}" | nc -cu 192.168.1.1 7000 tee console.log
)
I reset AC's wifi config, connected to his wifi, and used the command
I get response {"t":"ret","r":200} (which indicates success), but cant find AC's mac address in devices connected to my wifi

1. I've done it with official app and device connected with this wifi so I know it's possible, no problems with wifi, its 2.4, pass and ssid is correct
2. i double checked that i connected to the right wifi when I was searching for my AC mac address
3. i know his mac address because I've sent him get request via Python, when was connected to his wifi and got this response:
   {'t': 'dev', 'cid': '502cc6689819', 'bc': '', 'brand': 'gree', 'catalog': 'gree', 'mac': '502cc6689819', 'mid': '13000', 'model': 'gree', 'name': 'c6689819', 'series': 'gree', 'vender': '1', 'ver': 'V1.2.1', 'lock': 0}

maybe I'm doing smth wrong or you faced the same issue before and know the answer? i would be really thankful for any help
