2 days agoMy passiv cooled Pi5 (case as radiator) with HA is at 44°C (room is at 33°C). Idk how hot it gets on a regular basis, I just enabled the system monitor integration right now.
I mean with CPU temps, thermal throttling starts usually at 80°C, so nothing to worry.
Yes, they are different. I thing your “IKEA pairing” would be touchlink paring. I would say connecting the device through the controller offers the most flexibility. When you use Zigbee2MQTT, you can take a look at https://www.zigbee2mqtt.io/supported-devices/ what your device exposes. Sometimes you could loose a feature. For example the “VINDSTYRKA air quality and humidity sensor” can be connected directly to the STARKVIND air purifier, so it uses its value for the air quality. I never tried if I could connect it both ways.
On the other hand there is my Paulmann RGB remote control. I could connect the remote directly to lamps. I decided to do the automatons via HA and it has 116 different actions. Obviously its quite the task to do the automations, especially how I need to access the values.
But to not frighten you, its not always complicated. I have a few buttons and they aren’t complicated. Connect through Z2M, press every button in each variation (single, double click, hold), add the automation and then what happens.
You can make it more complicated (and fun). My hue dimmer switch could have 5 scenes via the hue hub but not via HA and Z2M. With Node-Red I programmed a small logic, that just counts how often I pressed the on button, within a certain time limit. It then cycles through my selected scenes. I can add as little and as much as I like. Oh and to clarify: Node-Red can be added as Addon to HA. It allows node bases programming. I find it easier then HA Automation, because it looks visually clearer. Also its way cooler, because it has more options.
