zigbee2mqtt VS deconz-rest-plugin

Have you considered Zigbee2mqtt[0]? You'd be running an extra program, but the docs are really good, it's pretty lightweight, and MQTT is incredibly easy to talk to from python or basically anything else.

For Zigbee, I can recommend using the Zigbee2MQTT (https://www.zigbee2mqtt.io/) integration instead of HomeAssistant's built-in ZHA system. It might be a bit more complex to set up, but it's very powerful and works fantastically. (User "simon42" on YouTube has some good videos about the topic, but they're in German.)

This is definitely better than many of the alternatives but still not perfect. With Zigbee etc you end up locked into one or more of the ecosystems, not to mention some manufacturers implementing it in a way that has weird quirks (see [1]). With esphome you have a limited choice of devices (would love to see more), but you also usually end up locked into keeping a 2.4GHz WPA2 AP for your devices (and you miss out on mesh, but also the problems when it doesn't work...)

You can keep your Hue bulbs and devices but threw away the app, hub, and need to work with hue as an institution at all.

I got a $30 USB zigbee stick to replace the hub. works great!

It looks like it uses zigbee? If you have a server you could run zigbee2mqtt. You'd also need a zigbee dongle / adapter.

If you want to use HA on your phone, you would need to install it on the pi, along with either ZHA or Zigbee2MQTT for the Zigbee network interface. Debian alone won't be able to interface with most of your smart devices.

I still haven't understood if the devices will change the path using the better route or not (since I've just tested a bTicino switch K4003C and it keeps using the worst path with 1 or 0 signal quality over a near Ikea repeater with a signal quality of 50).

You could try putting in an issue here: https://github.com/dresden-elektronik/deconz-rest-plugin/issues

I'm pretty sure it's supported by deCONZ. If I interpret this github issue correctly, it seems that support is included: https://github.com/dresden-elektronik/deconz-rest-plugin/issues/3827

The Aqara ones I use have configurable sensitivity.

They are newer, yes. But other than that, The Conbee can have 512 devices (changed in 2.14.4: https://github.com/dresden-elektronik/deconz-rest-plugin/releases/tag/v2.12.4-beta) opposed to the sonoff : https://notenoughtech.com/home-automation/sonoff-zigbee-3-0-usb-dongle-plus/ which seems to have a 200 device limit.

Not sure about the other items you list -- if they support Zigbee, they'll probably pair just fine. Here's a page where you can see what devices are compatible with the ConBee: https://github.com/dresden-elektronik/deconz-rest-plugin/wiki/Supported-Devices
