I run Homebridge on a Mac Mini running Mojave.
Did an update to both Homebridge itself from 1.2.x to 1.3.x and a few plugins that were out of date.
I have Z-Wave blinds via a Hubitat hub that work fine via the home app directly but Siri will no longer do so by voice. Says there is no response from the blinds. Similarly a Philips dimmer (via hue bridge homekit) will no longer raise/lower them when I push the buttons Ive mapped in homekit to open/close them. 2 other buttons do work for lights also mapped to the dimmer, so the dimmer itself is responsive, its just not firing the blind commands.
The blinds are exposed via the hubitat-maker-api plugin and it was updated for the first time in awhile so it may be an issue with it. Whats got me stumped is the device still works through home app if I manually hit its icon in the app, though there is a bit of a delay. I can even go into the blind and raise to a specific % and its responsive. Its just the "automations" around it (Siri and Homekit switch mapping) aren't working.
Ive tried restarting my Mac/Homebridge and even my router (eero Mesh) thinking it might be network related. A Zwave doorlock also using the maker-api plugin is similarily still kinda working. Siri will tell me if the door is locked or not, but if I ask it to lock or unlock the door I get a similar not responding error message, yet I can do so via the Home app directly. Its also giving the locked unlock notifications properly... Just very strange that Siri and automations are no longer working.
I just updated hubitat C5 to 2.2.6 as well. Not sure if there was an update to the maker-api app on hubitat though.
