Mysterious error message

[pittbull]

I'm seeing this error repeated throughout the day, yet there is nothing wrong with my Netatmo sensor. Any insight?

The screenshot is from my slack channel but the same is reported in HA.

@pittbull you probably need to have a look at or adapt the flow that is setting the alarm (ref. fig. below) I'm using the netatmo as default input to the outdoorcompensation calculation due to temp. dips in the VTR300 inlet, caused by the inlet location above the/my main/front door. (ref. readme "Aktiv utetemp.(Active outdoor temp. sensor"). If you dont need or want this feature, you need to adapt it to you requests.

If the netatmo outdoor temp. fails The alarm is set and the VTR300 inlet temp is given to be the new "in charge" (input) to the outdoorcompensation calculation if the Netatmo outdoor temp. is not changed within 2 hours, it happens once in a while that the netatmo outdoor temp. freeze (in my case, ref. fig. below). To prevent one alarm for each 10s poll, is the "Rate node" limiting the number of alarms in HA. I now see that the rate node should have been reset when Netatmo "is back" (changing value within 2 hours.) A reset message to the rate node (send msg.reset) will prevent one un-wanted alarm after 6 hours.

If i understand you correct, are the system throwing out this alarm continuously or with high frequency. From my perspective is this due to the fact that the netatmo temp. is not changing within 2 hours or because you need to adapt the system to your system. But as mentioned, a reset on the rate node would reduce one (1) unwanted alarm after 6 hours,

I hope that helps you on the way.

Frozen value for loonger then two hours:

Aha. I see. I have my inlet placed in a different spot so this will not be a problem for me.

I am not sure though what I need to change.

@pittbull

1. Backup

2. Delete all the nodes except for the "Utekomp: Kalkulert tilluftstemp [°C]" (ref. fig below).

3. Import the flow below (ref. fig. & flow).

4. Replace the debug node with the "Utekomp: Kalkulert tilluftstemp [°C]" node.

5. Remove the following entities from UI "Utetemp_sensor_status" & "Utetemp_sensor_valgt".

That's pretty much it unless you have made other changes that i'm not familiar with. Hope it helps out.

New node flow:

Cool. Will try this when I find the time :)

[pittbull]

Works! :) Thanks.
