I am trying to build a changeover box to switch between 3 power sources.
So our house has a single-phase power connection but sometimes the phase would go down at the distributor and we would lose power. And, our house is the most unlucky one as every time it’s our house phase that goes down, an electrician would have to climb the power pole to change the phase wires.
So what I am trying to do is have a junction box, where all 3 phases (4 wires) come to and then output a single phase (2 wires) to my house.
I am trying to do it just with ESPHome automation as I don’t want to rely on HA for it.
While I can get it to switch it’s not very consistent and I am looking for someone to take at it and maybe give some better alternative.
The flow is like this
Phase 1 has power, so output Phase 1 (Reference)
Phase 1 is down and Phase 2 has power, so output Phase 2 (Secondary)
Phase 1 and 2 are down and Phase 3 has power, so output Phase 3 (Tertiary)

I saw the script was slow for the third switch and instant for the first. I added a 2-second delay to the first switch and it stopped switching. (Maybe the script is triggered over due to the sensors updating voltage continuously).
I made some updates where I interlocked some of the relays and removed the delays from the script. It works much better now, but I would love that delay to prevent any short-circuit
