large temperature increases

[swoopdk]

Hi all,

First off i'm quite new to both Home Assistant and smarting my home in general apart from some lights through Hue in the past.
So i have recently installed some cheap zigbee Thermostats ( https://www.zigbee2mqtt.io/devices/GS361A-H04.html#siterwell-gs361a-h04 ) and they seem to work fine. However I was not happy with the fact the triggering temperature is right next to heating source as it was causing huge spikes of 3+ degrees when heating. So i found BT allowing me to use the room sensor to balance things. However i'm still at times seeing some huge spikes causing me to worry about the settings i'm using (or perhaps a bug?).

Last night we had two spikes in temperature and as you can see the triggerpoint is 19 degrees and it heated the room up to 22 degrees before stopping off. And again we had a spike later in the evening where the temperature was nowhere near the 19 degree target.

Here is how the graph looks inside the actual thermostat entity

Here is my settings in BT

I have today tried to look into Overheating protection but i'm not sur if it's designed to mitigate the issue i'm seeing here ?
Also should i try the "normal" calibration mode ?

What i'm hoping to get is two things.

1. I have the window sensor turn off h eating when opening the window and then not turn back on until x time later to avoid a surge right after airing out the room. (i see that i'll need to follow this here as i don't want to leave it open except afterwards to let the temperature 'settle' (Independent delays for open/close window #883))
2. To maintain a steady temperature with smaller regulations so i don't have crazy temperature swings.

Am i going about it wrong.

Show the BT graphs please.

Try overheat protection. Seems like you TRV doesn't close the valve.

Ah sorry i didn't even realise i had a seperate graph there.
Should be this one ?

From what i see it does close even quite quickly but perhaps it just does extreme heating (100%) during the time ? It starts heating at 7:52 and if i'm understanding the graph closes 8 mins later at 8:00. So eeven though it's only ~8 mins if it's 100% open during this time it's most def the cause. Is there a way of seeing how open the valve is ?

I'm trying now for a 24 hour(ish) cycle with overheat protection enabled to see if i get a more steady graph over time. I have two rooms with similar patterns so i can hopefully get some good data here.

Hi, do you have any solution? I have the same issue. Thank you.
