  • Can you not see in the activity log, either of HA itself or of the device, what is causing the action to be carried out? You could go to the device and check which automations the device is part of and check their traces as well, if you have recollection of when this last happened.

    If it is a backlog of stuff, maybe restart Home Assistant, or better yet, the server itself. But it shouldn’t be sending those to other devices.

    What’s also possible is that something is up with the electricity in your home. Maybe these devices are getting power surges or cutouts and defaulting to whatever you have that Power On setting set to. I think the default setting is that devices like that go back on after power loss.

    Last thing I can think of is an errant Zigbee controller. Maybe it’s picking up Bluetooth or WoFi signal interference and sending garbled messages to anything that’ll listen.

    Or someone outside is trying to mess with you but without physical access to your Zigbee hub this is next to impossible.




  • Considering the raging success of Borderlands 2, I feel like TPS was more than serviceable. It was received quite badly, even though the gameplay was the same as 2 and the story was at least 65% as good as 2. Maybe the playable characters were not as great. But the world was very well crafted and I actually loved the way the Eridian arc was so much more present, even though there is no Siren character.

    I’m currently doing 4. It feels like a soft hommage to the first game, but it also has some references to TPS. But it also feels like it was made for people who don’t even know there are previous games. Of course, the ones who played the original are maybe outside the target demographic, which was already the case with 3 going by the villains of that game.

    In short: I still love all Borderlands games equally and The PreSequel is definitely up there!






  • ‘Big’ is relative. It’s a house in between two left and one right in a block of four. It’s big enough for two people, but it’s not huge.

    I’m not sure I understand the function of the buffer mentioned. Is it a heated buffer that can pump around hot water without having to expend gas to heat? How does that differ from the expansion vat I have? Is that just to soak up excess pressure?

    Sorry about all the questions, I’m just not sure about all of this stuff.



  • There is only one TRV in the living room because the other valves are not thermostatic. I would need to replace those to achieve what you describe. But then I think that’s not the way to go because it could damage the pump from what I hear.

    The boiler is a Remeha Tzerra Ace which supports Opentherm with modulation. It’s also wired on the opentherm contacts and the T6 supports it.



  • The issue I’m trying to solve is to heat a room upstairs whilst not having the boiler in a constant ‘on’ state (the main thermostat is modulating and uses OpenTherm to communicate but that’s beside the point).

    A use case: say I’m going to work in my room upstairs. It’s currently 18°C. The living room, where my main thermostat is, is 18°C. I have my coffee in the living room, causing my automation to recognize I’m in the living room.

    I move up to my room and set my comfort temp to 20°C. The thermostat in the living room adapts to that. So does the TRV in my office. Since the setpoint of the main is higher than the measured room temp, it sends a heating request to the boiler. One of the radiators in the living room is closed, since the presence detector don’t show occupation in the living room.

    In this case, my office might not make it to 20°C before the living room does. The pump stops and no newly hot water gets sent to my office even though the valve is open.

    Bottom line: with the current blueprint I mentioned, everything works moderately well. What I want to avoid is to have the boiler heating water if the only occupied room is already at its setpoint. What I want to achieve is more control over when the boiler should heat water (and also pump it around) so that I don’t have to heat the living room when heating, say, the bedroom.

    Oh and as far as the time between presence sensing and heating goes: I’m fine being a little chilly for ten minutes. Like I said, I keep every room at a minimum of 18°C to make sure it never takes too long to heat if I want it.
