Patricen1 commented 2 years ago

Hello,

Since a couple of days, there is an issue when controlling air conditioner. Status is correctly uploaded to Domoticz, but when trying to control air conditioner from Domoticz, the following message appears in the log and there is no effect on the aircon system : "MELCloud receive unknonw message with error code 500".

Has anybody got a clue regarding this issue? Thanks

It looks like MELcloud does not accept urlencoded forms. I have created a quick-and-dirty (very dirty) fix by replacing the urlencoded form with a json one. I don't have a time for patch or pull request now, so you have to edit plugin.py manually

I also don't have time to check the whole code now so I don't want to patch the original melcloud_send_data function as it is used elsewhere. So copy the function melcloud_send_data as melcloud_send_data_json and change the content-type from application/x-www-form-urlencoded; to application/json;

def melcloud_send_data_json(self, url, values, state):
        self.melcloud_state = state
        if self.melcloud_key is not None:
            headers = {'Content-Type': 'application/json;',
                       'Host': self.melcloud_baseurl,
                       'User-Agent': 'Domoticz/1.0',
                       'X-MitsContextKey': self.melcloud_key}
            if state == "SET":
                self.melcloud_conn.Send({'Verb': 'POST', 'URL': url, 'Headers': headers, 'Data': values})
            else:
                self.melcloud_conn.Send({'Verb': 'GET', 'URL': url, 'Headers': headers, 'Data': values})
        else:
            headers = {'Content-Type': 'application/x-www-form-urlencoded;',
                       'Host': self.melcloud_baseurl,
                       'User-Agent': 'Domoticz/1.0'}
            self.melcloud_conn.Send({'Verb': 'POST', 'URL': url, 'Headers': headers, 'Data': values})
        return True

Then change melcloud_set as follows (you may keep the old code as melcloud_set_urlencoded just in case):

    def melcloud_set(self, unit, flag):
        post_fields = "'Power':{0},'DeviceID':{1},'OperationMode':{2},'SetTemperature':{3},'SetFanSpeed':{4},'VaneHorizontal':{5},'VaneVertical':{6},'EffectiveFlags':{7},'HasPendingCommand':true"
        post_fields = post_fields.format(str(unit['power']).lower(), unit['id'], unit['op_mode'], unit['set_temp'], unit['set_fan'], unit['vaneH'], unit['vaneV'], flag)
        Domoticz.Debug("SET COMMAND SEND {0}".format(post_fields))
        self.melcloud_send_data_json(self.melcloud_urls["set_unit"], "{"+post_fields+"}", "SET")

EDIT: it seems MELcloud is validating the json syntax so I had to make some changes (lowcase for power, single quotes)

Hello,

I have tried but it does unfortunately not operate properly (maybe due to a bad paste from my side), see log below.

By the way, it looks like there is some knowledgeable people there, would it be possible improving the plugin using a setpoint type device for temp setpoint instead of a multi level switch?

Did you left the original melcloud_send_data function intact? You are supposed to copy it and then change the name and content type, leaving the original function as it is, because it is used elsewhere (during login process, for example).

You can probably make a script to synchronize the selector values with a setpoint.

Patricen1 commented 2 years ago

It looks like I did not catch something. Could you please share your plugin.py file? Thanks!

When using the latest plugin version, I get others errors, like described in #24 and #22 I'm using latest stable domoticz version, v2021.1 build 14119). Using plugin version 0.7.6 the problem is not present, the device I have is found but I continue getting the 500 error. Using latest 0.7.7 with your proposed change on plugin.py or uploaded one, problem goes away but no device found in the building and error mentionned appires. If anyone can explain it...

mitkodotcom commented 2 years ago

It's hard to say. Unfortunately the debug setting does not work so you have to uncomment Domoticz.Debugging(62) or Domoticz.Debugging(-1) in my file and restart.

Try not to use areas, only floors. Do not use any non-ascii characters in names.

Xavier74 commented 2 years ago 
  Many thanks, updating to floor instead of area and applying the new plugin.py worked :)

Thanks for this fix. It made me able to controle the airco's with Domoticz again. I do get the errors below. Any idea how to solve these?

The given file works for me (only tested on a standard use case start/stop) ! Thx a lot :)

Note the given file also includes the changes relative to https://github.com/gysmo38/domoticz-python-melcloud/pull/25, and I'm waiting to see if it crashed after some time or not (ongoing test, I'll let you know).

As I was facing the same issue as several, I dig a bit in the plugin, and rewrote a bit the login function, to use json instead url-encoded logic. I also adapted the device discovery process to be able to discover my devices.

Here is the modified file: plugin.py.zip

I'll try this! There are some things that looks strange to me regarding Melcloud.

Thanks!

Hello,

Thanks to @mitkodotcom for the quick fix, it worked well for me. I was previously on version 0.7.6

Hope the plugin will be updated properly :)

Gracias Patricen1, gracias a tu archivo todo funciona a la perfección.

Hello,

Today, I tried to solve a hearbeat problem with a rewrite of the heartbeat management. I implemented a parameter to choose the interval. I also implemented multilingual support with the MELCloud app.

Thanks for correcting error code 500 ;)

Have fun ;)

EDIT : after few fixes... v0.8.2 based on Nonolk version : plugin.py.0.8.2.zip

EDIT : and v0.8.3 based on Mitkodotcom version : plugin.py.0.8.3.zip

I'm afraid none of the solutions work for me. When I try the latest plugin.py in the post above, it gives me a lot of syntax errors: 2024-11-05 17:22:24.074 Error: Airco: ValueError: invalid literal for int() with base 10: '' 2024-11-05 17:22:26.170 R-Pi sensors: Temp (Internal Temperature) 2024-11-05 17:22:26.178 R-Pi sensors: General/Percentage (CPU_Usage) 2024-11-05 17:22:34.090 Error: Airco: Call to function 'onHeartbeat' failed, exception details: 2024-11-05 17:22:34.092 Error: Airco: Traceback (most recent call last): 2024-11-05 17:22:34.092 Error: Airco: File "/home/pi/domoticz/plugins/domoticz-python-melcloud/plugin.py", line 656, in onHeartbeat 2024-11-05 17:22:34.092 Error: Airco: _plugin.onHeartbeat() 2024-11-05 17:22:34.092 Error: Airco: File "/home/pi/domoticz/plugins/domoticz-python-melcloud/plugin.py", line 440, in onHeartbeat 2024-11-05 17:22:34.092 Error: Airco: self.runCounter = int(Parameters['Mode2'])

Any chance of a proper cleanup on the plugin?
