I recently replaced my old Honeywell thermostat with a T6 Pro Zwave. If I use the stat on its own, the schedule works fine.
Once I add it to HA via ZWave, it seems to report fine, and I can control it. However, as soon as I try to create a heat/cool schedule for it using the Scheduler Component (GitHub - nielsfaber/scheduler-component: Custom component for HA that enables the creation of scheduler entities) then it acts up.
I define the schedule, and immediately the Heat is off by 1. Last time this happened, it wouldn’t auto switch from Heat to A/C later in the day, so I totally reset the stat.
Is there something I’m doing wrong, or is there a better way to schedule heat/cool times with ZWave?
Again, if I use the scheduler, I can set it to a certain temp. But once it’s applied, the stat shows 1 degree cooler than what I set, and it overrides. So the next morning, despite being told to heat to a certain degree, it will be one degree lower.
First, you should disable all schedules that are on the thermostat and make sure it’s not set to any preset. In HA developer tools / states look at the climate entry and verify preset is none.
Also I have noticed that the T6 display is sometimes wrong. So when it’s in the state you see compare what its display says vs what HA says it is. Refresh the entity from zwavejs also.
When I join it to ZWave it disables the stat schedule. I enabled the schedule because I want it to run in case my HA server is offline for some reason.
So far I’ve not seen any presets listed in HA. And the stat schedule should be the same as what I’m trying to configure in HA.
For now, I’ve disabled the scheduler component. I’m trying regular automations in HA based on specific start times so we will see if that works.
I’ve been using the Scheduler component with this thermostat for a year now and have not experienced this. I use “Make Scheme” and then “Heat/Cool” and set my temperatures that way and it has always matched the display on the unit. I have not used any presets, and have separate automations for vacation/away that disable the schedules in those scenarios. I have seen that the thermostat has a bunch of ZWave parameters that can be set but I have never touched those.
