    Great stuff thanks Rameses, put me down again for beta testing if it's an option like last time. Cheers

    I kind-of disagree with that one. The main install manual is pretty damned good, I reckon, with a good mix of the simple and advanced stuff.

    It'll never cover everything, and it would be a mistake to try to do so.

    I have to agree with G4RFL - I have had plumbers and electricians trying to figure out the system from the manuals and fail almost every time. I am an IT Manager with 30 years experience and I found very them confusing until I finally understood the whole system. Just look at the number of posts about config, double bindings etc., people are struggling - ANd its not the technology, that is logical its the supporting docs and guides.

    Sorry but the manual does need attention. What it says is correct but one has to real concentrate to realise the sequence. If somebody else can post a clearer instruction, as happened here a few years back, then it shows it can be done, and is needed. When my system was installed I did most myself but played safe with the final connections with the relays and the boiler. I sought the help of a “panel” Honeywell approved installer. He had not come across the system. He could not work it out from the manual. I ended up explaining it to him and carefully going through the manual line by line to ensure the sequence was right. The layout on the pages is just not conducive to ease of understanding. Miss one bit and you are in trouble. As the postings in this forum attest.

    Been a long time since I've read this forum coz EvoHome simply works - fantastically :-)
    12 rad & hw closed setup with modern boiler - been in for 4 years.
    Unbelievably reliable in all aspects. And the hr92 low battery advisory makes the running maint a breeze.
    I use Domiticz to see all the graphs and you can see how well EvoHome does at managing the temp/timings for every single room.

    But, I agree about the installers - they are plumbers/heating 'engineer's - not IT specialists... they found it so difficult I took over and did the setup.
    and the manuals only made sense after weeks of getting it where I wanted. And I (like others on here) am very tech/IT savvy.

    So to read the opening post about it's been a succesfull product and it's life is far into the future is good to see.
    Good to hear the App is changing - it's very simple and outdated.

    I have it linked to Alexa and that is the cherrry on the top. Daughter says "it's cold in here" - I say "Alexa, what's the temperature in the Living Room" :-)
    Even Alexa groups like "Alexa, set Upstairs Heating to 21"

    Back to long term lurking mode again ;-)

    Default Api

    @Rameses: One thing I'd love to get closure on is 'formalising' the API.

    I write Alexa skills for a living and I want to release a non-affiliated skill to control Evohome, but I don't want to put in the development effort if an unofficial API key can be revoked at any moment. The official Alexa support to date is very basic. You can query the setpoint/actual and adjust the setpoint and that's it. With my skill you can edit and query schedules, save and restore entire named schedule-blocks (to e.g. switch between a day-shift and night-shift), delay or pull forward things like going to bed or getting up (Alexa, delay bedtime by 20 mins; Alexa, I want an early rise tomorrow by 45 mins). There's a concept of scenes, which simply map to named setpoint groups (Alexa, activate watching TV). Plus some energy-saving helpers like Alexa, what rooms have heat demand? It's all user customisable and groups/scenes can all be named to the customer's desire (by voice). If you have more than one Echo then you can omit the zone name in the command as there is an 'assumed' default zone for each Echo unless a specific zone is named in the command.

    None of this is rocket science - in the end, the skill code just queries and modifies the JSON data that's already sitting in the Resideo cloud. But it does clever things with that data in a manner that's really easy for a customer to use. It's a custom skill rather than the smart home skill that Resideo provides for Evohome, which explains why it can do a lot more. I'd like to make it available under a freemium model if an API key is a realistic proposition. The API is 'there' anyway and it's used under the hood by the Android and iPhone apps. Surely it's low hanging fruit for Resideo to leverage that API investment and open Evohome/TCC to the maker community?

    Respect @philchillbill
    What a fantastic implementation.... Gets my vote for general circulation.
    I have an API key as I pull in all my data for more general house usage.
    If you feel like sharing please include me on the list and I'll use my own API key.
    Thanks.

    Sounds like Resideo should buy your code!

    Is there a way to alter the min DHW Temp ? My Boiler comes on after two showers, however I have a Solar Immersion that heats the water during the day, the min water temp is not an issue for me, so I'd like to set it lower.

    Thanks,

    FLY

    Minimum hot water temperature is set indirectly by changing the differential. Minimum = setpoint - differential, so increase the differential number.

    Keep in mind that if the minimum temperature is too low and hot water usage is low there is a theoretical increased risk of Legionalla.
