Router Connection to Honeywell Evohome not working

[Midori47]

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.

I don't know anything about the Evo home system, but do have a friend who uses Honeywell controllers on his home heating system, and can control each individual radiator and towel rack, and has "zones" set up within the house. All controlled from his iPhone.

I can't quite understand why knowing the external temperature can "optimise" that.

I really don't see how being on Vodafone could stop your system from getting details from Accuweather, presumably you have some form of account at Accuweather so they know who/where you are.

I doubt any system would use Geolocation for such a thing, as it is well known to not be accurate,

As far as I understand from Honeywell Support Evohome Total Connect Comfort Intl. is the Corporation responsible for feeding their Evohome Controllers all around the world with timely firmware updates, improvements, and ambient temperature. Users register their device and postcode, from which which information ETCIntl  injects the latest revisions, plus the hour by hour ambient temperature to all users worldwide. They told me they source the worldwide temps from Accuweather, Seems great to me. I have the latest firmware too.

Yes, few users (like me) perhaps seldom check their local temp on their Evo's, but the data is used to advantage by their Evo to save energy. For example knowing that outside temp at night reaches to say -3C or +10C enables the Evo to optimise starting the boiler, and visa versa.  If user's disagree, the can toggle it off but as I majored in IHVE at Uni, I know it a real benefit.

I thought I'd try asking the "new Bing" A.I.. how EvoHome knows the outside temparature where you live, and it said this.

"Evohome knows the outside temperature by using a weather service linked to your location zip-code. It also has a cold weather boost feature that adjusts the programmed setpoint based on the outside temperature and other factors like draughty windows . Some evohome systems may also have an outside sensor that measures the outside temperature directly "

So basically it should know who you are, and for some reason it is currently unaware of who you are.

It also pointed me here: How does the cold weather boost feature of evohome operate taking into consideration outside tempera...

[Midori47]

Yes. exactly like that. But Honeywell DOES KNOW who and where I am by my account registration. And it works perfectly fine updating my firmware in  background.  They would have asked if it was lost.

They are at fault in my book, but whilst I know nothing about protocols and ports et al, I have to look for the definitive solution.

What would be the best way forward? Spend more days requesting Vodafone for a static IP address, or learning how to identify ports and stuff?

[Jayach]

I very much doubt it is because you need ports forwarded, otherwise how are you getting updates?

Getting a static I.P.. should be no problem, just ask via live chat. https://www.vodafone.co.uk/bbservcd/, but I can't think it will help. (How do you inform Evohome of what it is?) 

[Midori47]

(How do you inform Evohome of what it is?) . 

That is beyond my expertise.

I got the static IP arranged within 24 hours. It was so easy and free of charge.

Thank you for guiding me.

But, has it helped with the problem?

@Midori47 Which Honeywell device is it? I spent a bit of time reading the R6 manual out of curiousity and that doesn't mention static IP at all, but it does mention the MAC address.

[Midori47]

It is as per this instruction leaflet:-

PS - My static IP address is set up already. However no difference !
