MELCloud linked to Mitsubishi Ecodan air source heat pump lost internet connection- Won't re-connect?

I have MELCloud linked to my Mitubishi Ecodan air source heat pump.
Recently I lost the internet connection and cannot establish a reconnection.
My connection is via Access mode as my router does not have a WPS button.
I am able to complete the process for reconnection correctly but it does not connect.
I have previously been successful and there are no changes to my home network settings.
I am wondering if;
the MELCoud server is down?
or if I have a non standard password to my home wifi network - it includes a ’ and has a space in it?
Any help with reconnecting to the internet would be useful.

It seems to be a wider issue as there’s an update on the support page. 
 

not sure I believe the ‘relatively small’ numbers affected. 
 

I can’t find anyway to submit a support ticket.

Update: the installer has submitted a warranty replacement request to Mitsubishi for my controller unit claiming it’s the wrong one.  I’m awaiting the outcome of that, although I am a bit sceptical about it.  The install manual mentions a DIP switch that switches on energy monitoring, but it’s unclear if it’s needed to be on if using the built in energy monitor or only when separate monitors are attached.  Does anyone happen to know about that I wonder?

For clarity, when the controller works I’m expecting this to be the only way I can see energy data.  I am not expecting that it will work via the MELCloud app, which will be pretty disappointing.

The EMP2 or EMP3-M energy monitoring packs would be needed to view it via MELCloud .  My installer said this would cost £800 + install cost.

I’m keen to get the thoughts from some other Ecodan members on this, @lycandroid.

 

@christianedward @hambrook any ideas about energy monitoring?

Just called the Help line at Mitsubishi as I have also had this problem and the phone assistant told me that the MELCLoud is down and its a known problem so nothing we can do until they sort it out at their end 👍🏼

Good to know @BrightonCouple. I haven’t had a response from a support ticket sent 3 days ago. 
 

Pity they couldn’t send out a notification email to save us having to work it out.

The connection to my MELCloud has now reconnected. 
This has happened remotely as I am away from home and I simply left the dongle in a failed reconnection state (flashing ERR light).

I am now getting the usage data and the wifi signal strength is displayed. 👍

Hi everyone, sorry to jump in on this thread. Our new ecodan was installed yesterday and all seemed fine. Woke up this morning and looked at the report to see it seems to have turned itself off? Wondering if anyone has any ideas. We're away so can't physically look at any of it. Has the WiFi connection with the ecodan just been severed, or perhaps it's a power outage/fuse?

There are a whole bunch of reasons why it might have switched off. Unfortunately it's impossible to diagnose them without seeing the system and controller

Hello all,

I’d like to find out if any other Mitsubishi customer is experiencing the same issue of mine: the app MelCloud seems to be no longer able to communicate with both units I’ve installed indoor. All was working fine till 2 days ago: nothing changed in my hardware or configuration. The only update I’ve done these days is to bring my router to Fritz!OS version 7.50 from 7.29. Both the units indoor are still visible in my Mesh network devices list and wifi signal is correctly active, in fact also MelCloud app is now reporting perfect Wi-Fi signal strength for the units. 


The issue with MelCloud is: Error “The unit failed to respond to the refresh request”


I suspect this could be an issue with the MelCloud app server rather than my units failure or local lan configuration issue. Thank you!!
