Not that I know what kohlchan.net/int even is or would visit it anyway, but why?

EDIT: This looks like a bot or spammer account since I see this in many many communities, so it’s either malware or some kind or click bait. So NVM, user blocked.

I think this one is a custom module, it solders into a slot on the main board vertically with pads on both sides of the modules bottom edge.

I also have a VPN set up to my home network that I can connect to with my mobile devices. once connected I use the HA mobile app pathed to my local HA server IP. I don’t use HA cloud or any other cloud service. It works well for me, I obviously can’t get notification on the mobile when not connected but I have not had a need yet. If/When I’m do want notifications I would most likely explore, e-mail, e-mail to SMS, SMS API or something that won’t involve external servers. I would not want to send sensitive info via SMS but a shot alert that said there is something to look at like “HA Alert: Motion detected cam 1” or such would be fine.

I just got a Filohome (tuya) dual switch and used tuya-cloud cutter put ESPHome on it. When setup with ESPhome it will still work even if HA is unreachable ok WiFi is down. I never even downloaded their app, made an account, or signed in.

Note for anyone trying to do the same, the Filohome triple switch device in tuya-cloudcutter will work to load the initial boot firmware but you need to change the yaml config when you install ESPHome. If anyone wants the yaml file let me know.

Eject the warp core!
