myVAILLANT integration

Hi there, How to get current flow temperature sensor?

I don’t use hot water, but I have the current flow temperature for circuit…

Can anyone help?

I have 600 for main update and 7200 for energy data, any less and I get quota issues towards the end of the week.

it’s sensor.<yoursystemname>_circuit_0_current_flow_temperature via the MyVaillant API, or sensor.ebusd_ctlv3_hc1flowtemp via ebus.

Is there any API entity that extracts current water RETURN temperature in heater, not only current flow temp ?

I don’t know whether Vaillant installations usually come with a temp sensor for return temp, mine surely didn’t.

I have a Vaillant AeroTHERM 10 kw with sensorComfort

I would to see live data of how much power my Aerotherm is using, but I do not see that in my Home Assistant.

I can see temperature of the water plus a lot of other stuff but I would like to see not when the it starts an stop.

Do you know if I can get those numbers with my setup?

I also want to measure the return flow temperature for my boiler. The boiler does measure this internally and installers can see this data with their diagnostic app. I got around this by putting a Zigbee temp sensor on the return pipe, but a bit of a kludge and would be better to extract data directly via API (if possible).

i have this problem !

Hello,
Facing the same issue. I am using this integration just to pair my Saunier Duval 18KKS with HA. Heating is based on the scenarios for every single room separately together with smart thermostats mounted on radiators.
With “My Home Zone 1” left in peace (heating permanently) everything is OK.
Manual changes to values result with disappearing of home integration.

With the integration being unavailable whole heating system is out of order.

God only knows what makes it come back. Just tried re configuring/ reinstalling or just waiting. But this is not how it supposed to be organised.
Changed seconds between the updates to 600 and it helped.

Right now, although changed to higher values the same scenario reappears.
Hints how to make it available are appreciated.

Dear all,

I’m using this integration since a couple of days. While the controller, the domestic water and the heating circuits are regularly reporting values, the heatpump itself has issue: While the diagnostics are updated from time to time, the sensors appeared, but whether receive data only once after reload of the integration, or not at all (maybe after a reboot?):

I assume this plays a role? Update interval is 300, update interval for energy data is 300 as well… maybe too often?

Can somebody help? The COP (“Heizeffizienz”) would be really nice to know… Thanks a lot!

Hi! I wanted to chime in to help troubleshoot.

I am running a fairly heavy setup myself (using AmbiSense with multiple zones), which typically generates more data traffic. However, I have not experienced any quota issues or 403 errors recently.

Looking at the error 403 Quota Exceeded, it definitely points to rate limiting.

I checked my own stable configuration, and I believe two settings are key to keeping me within the safe zone. Could you compare these with yours?

  1. Update Interval: I have set my “Seconds between updates” to 600 seconds (10 minutes). But I noticed in your post that this is already the case.

  2. Realtime Data: I have explicitly disabled “Fetch realtime statistics” and “Fetch realtime energy consumption” in the integration options. These can trigger excessive calls.

Try increasing your update interval to 600s and disabling the realtime fetch options to see if the error clears up after the quota reset.

Also do you only fetch data from the Vaillant cloud through the integration (HA environment)? Or do you use external means accessing Vaillant cloud, like connected with Google Home or Alexa?

Exactly what I did :slight_smile: purchased BleBox temp sensor, attached to return pipe and read it over WIFI :slight_smile:
