I'm new to netbox and as far as I can tell there are two ways to combine Netbox with ansible.

• Automate network and Netbox with ansible. A playbook would configure a switch port and then use the Netbox ansible collection to modify Netbox to reflect the change. All changes go through Ansible.
• Use Netbox as the data source for ansible. A playbook pulls the switch configuration from Netbox and applies it to the switch using ansible. All changes go through Netbox.

What would be preferred? Both solve the Problem of having to change everything twice.

I want to dip my toes into the smart home world and decided that I want to use homeassistant and primarily use devices based on zigbee, as I do not want to overload my wifi with a bunch of devices.

Smart plugs seem to be most interesting to me as I would like to have accurate power measurements for my homelab and applicances. The keyword is accurate here. There seems to be some science showing that the accuracy of smart plugs can vary a lot. I have read that devices that are flashed with the tasmota firmware can actually be calibrated. Unfortunately this firmware is only available for wifi devices.

So my questions are:

• Are there zigbee smartplugs that are known to be very accurate or can be calibrated to be very accurated?
• Is preferring zigbee over wifi actually a good Idea? I mean both use 2.4 GHz, which is known to be crowded. When will wifi smart home devices become a problem?
• Is a calibrated tasmota smart plug more accurated than a typical zigbee plug?
• Is this inaccuracy reported in the paper even relevant for non-scientific use?

I'm setting up an application using containers with ansible. I want to be able to set up the same application multiple times with a different set of variables. Is there a way how I could do this in parallel on a single host? I know I could deploy the same application n times on n different hosts, but what about n times on a single host? Is something like this possible? Doing it sequential obviously works, but it doesn't scale well.

This sub needs a little more deep and moody techno
