Hello all, I wanted to ask for some guidance, I am trying to reach home assistant from Slack. More precisely, I want to trigger a command from Slack which in turn triggers an automation in HA. I thought MQTT or a webhook would be great for this. Slack has a community extension for MQTT, but I have not had any luck due to some constraints. I tried the following: setting up the HA MQTT integration to listen to a free cloud MQTT server that I did not have to maintain, Slack could then send messages to cloud queue and HA would pick those up to trigger automations. Unfortunately the existing Slack MQTT integration can’t deal with the free domain urls as they have multiple special characters and ports which seems to throw it off. Web hooks are another option, but I am not sure of how to expose them without compromising my HA instance, which is on a Proxmox LCX. Does anyone know of guides I could use to achieve this without exposing my HA? I can only use Slack in this case due to a lot of other restrictions where I access it.
Second task, I wanted to add a redundant smoke/CO fire detector system. So not a replacement but an addition. I have pets at home and wanted to have a way to immediately know if a fire or CO issue is happening at home. It would be great if this alarm could send me a message on Slack which is the only external app I am allowed to have when I have to be in the office, but also in case I am out and an emergency happens. I actually haven’t done research on this one and know there are a lot of options. Mainly looking to see if any specific recommendations could be made for me.
