HVAC status updates take up to 25 seconds to appear in Home Assistant #114

Hi all,

thanks for the fantastic work on the ESPHome integration! I got it to work with a WeMos D1 Mini v4 over 5V on a Mitsubishi MSY-GE18VA.

Bi-directional communication works fine (in principal).

It seems to me it's polling only every 25 seconds. If I change the temperature using the good ol' remote controller x seconds before the next 25 time mark, it will update the status in HA in x seconds. Meaning, it's not a constant delay of 25 seconds. Or in other words: on average I have to wait more than 10 seconds for changes to appear...

I thought this could be an issue between HA and ESPHome, however it's not. Status updates when compiling in the web server component appear at the same time there as in HA.

My update_interval is set to 500ms. I tried lower and higher values and does not have any impact on the 25 seconds polling.

Wifi ist stable (strong signal -51 dB, no packet loss).

Can anyone point me in the right direction? Thanks!!

EDIT: added my device's ESPHome yaml below.

This is expected behavior. The underlying library takes a while for changes to get reflected, as it has to send the command, and then wait for the unit to acknowledge it. I haven't found a way to speed that process up.
