    UK vs EU. The UK versions have the display the right away provided the valve screw faces the bottom

    Yes it does. And infact when using OT you could quite easily have the pump on for most of the day because the Heat Demand is varied, rather than goes ON and OFF.

    Is your outside temperature updating when connected to the Vodafone AP?

    All my HR80s are from my CM Zone sets. The controllers are long gone but the HR80s are still the only radiator controller in my system. Just be careful, you cannot adjust the pin stroke on the HR80s,...

    For me that would be a massive backwards step. I constantly glance at the temperatures. I guess not many realise that an LED needs power to light up, an LCD needs power only to change what's...

    Evohome isn't moving forward. "If you aren't growing, you are dying" is the phrase that comes to mind. Which is why we think Evohome is on its way out. However even today there is nothing on the...

    I do believe that in order to get the best out of a zoned system you need to have a boiler system to match. Which is why OpenTherm does make sense, but I still think the boilers need to be able to...

    The boiler has no way of knowing how many zones you have or how many need demand. All it can sense is Flow and Return temperatures. So if the Return is not cold enough, it won't fire. And if most of...

    I have always said the "learning" feature of Evohome is overrated. I use Optimum End, but not Optimum Start.

    I would replace all devices that have a low battery as soon as its reported.

    You can't set demand, you can set the setpoint where you want it. And the HR valve will calculate the demand it needs

    Just unpair the HRxx valve from Evohome and control it directly via HA via the HGI80?

    Without knowing how your current system is plumbed and how it's configured into Evohome, it's impossible to tell what's going on. How many motorised valves do you have in the system? etc.

    I developed a similar technique but in reverse where I force a BDR91 that is controlling an UFH pump to stay on 100% even though the BDR91 wants to use TPI and tries to shut on and off.
  16. Electric zones don't fire the boiler, but I'm not...

    Electric zones don't fire the boiler, but I'm not sure you can bind an HR91 as an Electric zone. Try that first. Otherwise you can build an automation in HA that forces that zone to follow others and...

    All working. I'm so nervous about not being able to get the first widget back, that I kept it visible even when it wasn't working. Because I'm not offered it any more. The new widget is nice too.

    I've bought a box of 100 lithiums, and don't need those many. I'd be happy to split the costs with anyone else.

    You only need an RFG100 with the Evohome v1 ajd v2 controllers and not the latest WiFi version.
    Can you confirm the model number of your Evohome controller. Even a picture of it would provide a clue.

    Yes it's true, it does work when it needs to. So I guess that itself explains why I too haven't botheree much with this.
    Infact that is what provided the clue to the cause of the issue too. Its all...

    If anyone in the UK wants to split the cost of some Energizer Lithiums please let me know. They start to work out economical only when you buy them in boxes of 100! So perhaps we can group buy them.

    Yes a low battery somewhere in the system causes that device to cause an RF message avalanche and that jams the radio waves. I would say, check all your Evohome devices for low batteries and replace...
  24. CS92 enhancements - getting rid of the comms failures

    The HW CS92 is notorious for causing comms faults. I believe, the issue is actually at the Controller end rather than the CS92 end. The CS92 speaks very sparingly and even a single message lost by...

    I have a theory that comm faults are actually more noticeable when the system is OFF. This is because during normal usage there is so much of comms between these devices that they don't mind missing...
