My Smart Home Config

**Scroll down to problem encountered for TLDR**

Overview
I was using Athom Homey previously and it broke down.
Didn't want to spend too much as my automation is elementary
Researched quite a bit and chose Home Assistant as I've Python knowledge.
Hence, I need to un-pair and pair my devices ( mostly switches ).

Software :
- Hassio - Raspberry Pi 3 Model B and B+ 32bit
- Install URL ( https://www.home-assistant.io/getting-started/ )
- Using Sandisk microsd at the moment
- Using Wifi at the moment as I need to bring my PI + Aeotec around for pairing.
- Enabled configurator so that I can edit configs on the fly.

Hardware:
Raspberry pi 3b +
Aeotec Stick Gen 5

What I managed to install?
- MCO Home 4 gang toggle switch - MH-S314 ( http://www.mcohome.com/show_list.php?id=13&sid=15 )

- MCH Home 2 gang dimmer switch - MH-DT311 ( http://www.mcohome.com/show_list.php?id=13&sid=132 )
( I have qty:1 4gang and qty:2 2gang side by side and I managed to install one of each )

- Yale YMF40 with zwave module
( managed to pair using secure node after setting network_key at options.xml )

- another MCO Home 4 gang toggle switch - MH-S314 ( http://www.mcohome.com/show_list.php?id=13&sid=15 )

To Dos?
- I need to move my raspberry around to install all the 4gang and 2gang switched
- 3 Amazon Alexa for speech to control my lights ( I think I need to do the hue hack, not going the $5 route )
- Pair my Ring Pro doorbell
- Pair 'IR blasters' to regulate my aircond
- LG TV
- Backup my micro-sd so that I can restore on the fly
- Automate : Yale Door Triggers light at Living Room

Problem encountered
- Unable to pair one of the 2gang dimmer

- 1 of the dimmer that I managed to pair sometimes are not responsive
( meaning when I manual toggle on , nothing will happen and the toggle will revert back to original position, it's working now ( for how long ?  )

- Node 11 , 4 gang that I installed seems to be working after a reboot.
Do I need to always reboot the PI when I install 1 device?

- Yale Lock is not responding to unlock ( I managed to unlock a couple of times when I successfully installed it )
I did a toggle and this it the error msg https://i.imgur.com/DhU7fMe.png
