Is your Envoy connected via Wifi or cable? This could be a bad/slow connection to the Envoy.

[Jagermyster]

It is connected via cable. I noticed the slow connection, just don't understand why it is slow. The cable goes directly from the Envoy into the router, no issues with my internet connection. Can it be a faulty Envoy?

[vincentwolsink]

Usually a power cycle of the Envoy will fix the slow response.

[Jagermyster]

I did a powercycle 2 days ago because the integration could not be installed. After the power cycle it worked perfect. So it looks like my Envoy gets slow after a few days. Did a power cycle just now and keep monitoring it. Thanks for the reply so far!

[Jagermyster]

After the power cycle the integration fails to start now :( Edit: Another power cycle and increasing the maximum time to get envoy data to 120s worked. Still my Envoy is terribly slow.

[vincentwolsink]

Try to disable the realtime data in the configuration. And see if that improves things.
