IoT Devices
This page mostly serves as a refernece to myself as to what devices are where in the house, which ones to buy again, and which ones fail frequently. My smart devices are all on my IoT VLAN, meaning that their internet connections are all separate to the main LAN traffic and I can hopefully eventually wall them off from the internet, using things such as Local Tuya.
Devices follow a sequential numbering order, with a label on each plug. When a device is retired, the number can be reused, and the DHCP DNS assignment is also updated.
Although DNS should work, all devices are assigned a static lease. Lights start at .21, plugs start at .41.

Device Specific Notes
eLinkSmart BSD29
Sometimes unreliable connecting to Wi-Fi. Tried to flash with Pi Pico programmer with open source firmware, but don't think the Pi contains the right pins to drive it. Tuya cloudcutter worked fine.
TECKIN SP27
One of these has gone to the graveyard. It was broken and wouldn't stop switching on and off. Other one still works okay.
Useful Info
Make sure AP is not obstructed or you'll get horrible performance and loads of failed pings. Must be lack of MIMO as phone can do 2.4G fine.
Cloud Cutting
Can take apart devices but Pico won't flash them using the attached method for the eLinkSmart plugs they were susceptible to the Tuya attack, so slowly migrating.
Need to work out the Alexa integration.
Emulated Hue
- Setup with all plugs, only add lights to the room groups, all other devices manually switch on and off
- All Alexas need to be on the same VLAN atm, looking at a possible way to allow inter-VLAN communications so can put Alexa back on IoT VLAN
- Other approach might include the idea of multiple IPs on the
