How to keep data across HA restart (lemmy.world)

I'm pretty new to HA. I've set it up and I keep editing the confirmation and everytime I restart to apply the changes, all the switches, sensors and even the thermostat lose their values. The most annoying is the thermostat (classic thermostat entity) because I have to turn it on selecting heat/cool and set the temperature. Is there a way to keep all these values across restarts?

Edit: I'm using HA OS on Proxmox. All the sensors and switches slowly goes back to "normal" as soon as they publish their state, apart from some entities that have values provided by HA itself and not by the devices (like the thermostat).

The thermostat is an entity in HA, there is no phisical thermostat! It's a generic thermostat!

Ah, so your real issue is just the thermostat? Your OP made it sound like you were asking about all switches and sensors.

Is it just the setpoint that you're losing and not getting back after restart? I'm assuming it's getting the current temp back from the sensor just fine?

No, my problem is not just the thermostat! All the sensors and switches loses their state, but while they get them back in a while kapart from the battery powered sensors), the thermostat has to be set back manually.

Jesus, you're not exactly making it easy here mate. Feeding info piecemeal, to someone who's spending time to try and help you, only frustrates both of us.

Re the sensors and switches, you said they're all sending states via MQTT. Are they setting the retained flag? If not, that's the problem. If so, run a packet capture to see what's happening when HA restarts - maybe it's not querying MQTT successfully straight away or something.

Re your thermostat, can you post your config? There's a few threads on the HA community forums that are complaining of similar issues, with various causes/solutions discussed.

I'm sorry if you think that I'm wasting your time. From my point of view, it's the other way around since all it's written in the OP! And you still saying to run a packet capture means you didn't get the point or you know HA less than me!

Your OP says "everytime I restart to apply the changes, all the switches, sensors and even the thermostat lose their values". Later on, you've said that you configured all your switches and sensors to publish their states in MQTT. Hence why I'm saying you need to look at how and when HA is querying those states.

You've since clarified that the thermostat is a generic thermostat entity, where HA controls setpoint. Without having posted your config, I'm left to assume that HA turns your HVAC on/off based on a temp sensor state.

I've been running HA for many, many years, and am a network guy by trade. I'm only trying to help, but you're now assuming I'm either not getting the point or know less than you.

No worries, mate. Best of luck. 👍
