Solution

My Honeywell Evohome Home Controller for my home heating system relies on Internet WiFi connection to optimise heating according to outside temperature, The Outside temperature is sent to the controller by Honeywell/Accuweather by internet. This worked perfectly well for several years until I changed ISP from Plusnet to Vodafone. All other internet and wifi infrastructure in my home works perfectly well on Vodafone's Router.

My issue is the Evohome controller shows a successful connection to ISP Vodafone via my home wifi network but does not receive nor indicate my regional outside temperature. I suspect the outside temperature cannot ping from Honeywell through to the Honerywell Home Control despite it showing it as being connected.

I guess the issue is Router related. It's firmware is 19.4.0551-3261103

Just to be clear, my regional outside temp is not data from an outside thermometer. It is a temperature sourced by Accuweather for my region and that digit is fed to my Controller by Internet by Honeywell via Internet.

Best way to reset is with the recessed button on the back, holding it in for 10 seconds. You shouldn't lose your phone or anything else as the settings will be reloaded from their server. Effectively a reprovisioning.

Make a brew after reset as the router will go through a few reboots before settling down.

PPS The Evohome is fully working properly as regards all it's control devices, etc. and is connected to my account ok, but just does not receive the Regional External Temperature.

Surprisingly too, the User Setup document mentions nothing about such things as pings and ports IP's , I is just plug a play !

@Midori47 That's a huge manual, which part is the thing that is supposed to get the weather?

I'm not at all surprised that the static IP has made no difference.

Both UK and USA based users are complaining that the Honeywell webserver is sulking. Or, as they have written it, "again".

Did you have to repeat the connection steps shown here? https://www.honeywellhome.com/us/en/support/wi-fi-7-day-programmable-thermostat-register-11/

Did you look at the FAQ? https://mytotalconnectcomfort.com/portal/Home/FAQs

I do not want to foster any finger pointing. The latest reply from Honeywell/Resideo states:

------------------------------------------------------------------------------------------------------------------

" You can find the status of the Resideo Honeywell Home servers with the following link:
" https://status.resideo.com/

"In case you have checked this situation already with your internet provider, and they can confirm that all the "needed ports for this connection are available, yet the outside temperature value does not update, please send "us the following information:

"1. the internet provider written confirmation regarding the open ports to the network.
"2. photos of the Evohome device with time stamps, and parallel screenshots taken from the Accuweather app, "where the time of day is also visible.
"2.5, should it be possible, the photos from 2 also with the Evohome connected to a Hotspot network, not only "the local Wi-Fi, to ensure that all avenues are covered.

"Without this data, we sadly can't continue the investigation.

I did explain that 90% of their users may have never seen "Outside C" on the display, Not knowing that it should be there, or, wondering who would bother to read it anyway, Thus the lack of complaints does not mean all is fine.

Before going any further I have asked Evohome/Resideo to re-confirm the Ports numbers / Port Protocols that are required Open because is said nothing in User Documentation. I guess the ball will then be back in my court to set the VF Router accordingly.

Honeywell reply to my request for the Port Numbers and Protocols is as follows. (Note, there is no mention of 2445,5561, 5562, and their finger points of course to ...... ?).

"The port number needed for the Evohome has the number 443.

This being said, usually this information isn't needed, as the internet providers know which services would be required for smart home appliances to work."

@Midori47 Are all the status LEDs green?

My Evohome is not supplied with a gateway. The current Evohome is ATC928G3000 This update integrated the original RTG100 into the EvoHome and it has worked perfectly since I bought it early 2016 up until 2023.
There are no indictor status light on it. My Eco is "connected". If I disconnect & remove batteries for a few minutes to update its clock, then 8 mins after reconnection, the time updates to correct time, and the display shows it as " L " symbol Connected to internet, The VF Router shown it successfully connected also. I believe Resideo or Honeywell support should not be asking questions about a non installed obsoleted Gateway - especially since we exchanged confirmation on my ATC928G3000 a few weeks ago.

My power supply was cut off for maintenance this morning and has just been restored and the Evo is reconnected. The outage was about 3 hours. After reconnection Time setting was automatically incremented and the L 'wifi connected' symbol appeared. I then received an automated email message from Honeywell associating with account information. It reads......

Dear user,

We would like to notify you that the Total Connect Comfort service restored communication with the heating system installed in the following location:

Location: Home

Sincerely,

Your Total Connect Comfort team

The following link discusses this issue on the Evohome Support Platform, I searched there for help and got an immediate answer pointing me to this link. It is certainly very technical and in parts beyond my comprehension.

Note: there are 5 full screenfulls to page through !

"It’s a Vodafone ISP issue:" https://www.automatedhome.co.uk/vbulletin/showthread.php?6713-Evohome-Where-are-the-weather-related-...

@Midori47 It may be a VF issue. There is not enough evidence to lay the blame either way. Mind you if it eventually is proven to be VF I would not be surprised.

Resideo final position today is...

.".. we recommend in this case is to simply take your Evohome with you, and visit someone who does not have your current internet provider, to then connect the unit to their internet Wi-Fi network, to see if the same situation repeats itself, or if in case, the outside weather feature actually works.

As we haven't changed anything on our end of the software of the Evohome unit itself, nor the internet connection it uses, and the only factor that has indeed changed, has been your internet provider, and its rooter, we sadly can't see any other reason to the current situation.

If your internet provider can't help you further with this investigation on their part, please share with us any results that they did share with you, so maybe we could give you other pointers, in what you could actually ask them / have them do."

I guess the ball is in my court to find a nearby Evo User (Buckinghamshire) willing to do the test, or to raise an official support number with Vodafone.
