I am relatively new to HA and am looking for some pointers to get started. I have a setup working at my house with the existing Wi-Fi based hardware and it’s really impressive. My parents have been battling some mold and flooding issues at their rental properties, and I see a potential for HA to b…

May be a bit more expensive, but… why not a HA on an RPi for each building, and a smartthings hub + smarthings temp / humidity sensors as needed. Then you can join all the HAs into a single UI if I’m mistaken using GitHub - custom-components/remote_homeassistant: Links multiple home-assistant instan…

Question: Can HA handle more than one Z-Wave or Zigbee dongle at a time? What if I used one plugged directly into the system, and then two of something like this to connect a dongle from each of the other buildings over the network? https://www.networktechinc.com/usb-ip-lc.html

I have a z-wave dongle running on my home assistant server with home assistant running a a virtual machine on ubuntu 20.04. With zwave-js the system just works. I have about 14 battery operated water sensors spread all over the house. Z-wave is generally slightly more expensive than zigbee as z-w…

Get an Elk M1. It will work reliably regardless of the state of your HA controller and there is an excellent HA module for it. The only question is controlling the mini-split, if it will take a normal thermostat then the Elk should work. There are wired and wireless sensors for everything else o…

Can’t speak about Zwave… but there can only exist one Zigbee Coordinator in your config… Maybe two if you use different integrations for each one (one with ZHA, another with Zigbee2MQTT), but the setup and maintenance for that would be a hassle. You can have single coordinator, but a lot of “router…

[image] Oreo: Monitor temperature and humidity within the units, crawl space, and attics. You could do BLE also, there is several models of sensors available inkbird, qingping, xiaomi with even the possibility to update the sensor firmware (lywsd03mmc). The gateway could be an esp32 with an …

[image] 1technophile: Also you could consider Lorawan I had looked at this, but not into it too much. Is there a robust integration for this in HA yet? Any experience with or advice on where to start looking at sensors?

[image] Oreo: Is there a robust integration for this in HA yet You would need to go through MQTT locally (prefered) : Sensors ->LORAWAN GATEWAY with internal LORAWAN SERVER → MQTT broker → HA or use the things network Sensors ->LORAWAN GATEWAY → TTN → HA You will need to decode the payloa…

Also mysensors https://www.mysensors.org/ have a good range, but may be a bit more DIY than you want.

If you don’t mind diy, you can build your own lora sensors and gateway for a fraction of the price.
