SEA801-Zigbee/SEA802-Zigbee - Does not (directly) start heating in the morning

jeroen85 commented 1 year ago

Prerequisites

[x] Model name of your Devices: SEA801-Zigbee/SEA802-Zigbee/
[x] Output from Home Assistant Developer Tools state e.g.
[x] Output from Home Assistant Device Diagnostic from BT

Description

In the morning, when temperature in living room is lowered to about 19degC, the TRV does not open enough to heat up towards setpoint of 20degC (set at 5:30).

The local calibration value stays -1 until 8:30

More detail:

Actual TRV:

Temperature difference on TRV itself seems too small. So it won't heat / open valve.

I am also experiencing very sluggish start of the heating with this product (even without using BT).

For example, when using the TRV (directly without BT), Room is at 18°, heating setpoint is changed to 21°, heating does not start. I have to set heating to 25°, or briefly set the "boost" mode, to get the heating engaged. Tolerance seems too high. Only happens sometimes though.

I think this particular model needs a good and strong "kick" in the behind to get started with the heating (meaning a high temp difference), but once it's on, I found it to be quite reliable.

wtom commented 1 year ago

Yes, it's very bad. You need the AI mode. That helps for me.

Maybe i would also try to use target temperature based calibration. Because the range there is bigger.

jeroen85 commented 1 year ago

It's already on AI mode. Works pretty good normally, just not in the case I described above.

I don't like to use Target temperature based calibration, as other family members use the TRV to set temperature

wtom commented 1 year ago

Maybe you can check if the quirk is loaded for your model, because normally there is a quirk that raises the local calibration a little more.

jeroen85 commented 1 year ago

Yes, it does

Hello! Where can I see these DEBUG Log entries in Home Assistant for BT? Thank you!

jeroen85 commented 1 year ago

@Wennsday Go to Developer tools-> Services

Go to YAML mode and put this in, press Call service:

service: logger.set_level
data:
  custom_components.better_thermostat: debug

Wennsday commented 1 year ago

@jjansen85 Jeroen, Thank you very much!!

KartoffelToby commented 1 year ago

I also use this TRV myself. No problems. Just leaf all unchecked. Select offset calibration with ai calibration and everything should work

jeroen85 commented 1 year ago

It seems to have occurred once. Let's close this for now. Thanks
