Trying to setup HA to control my RV lighting. Having a hard time finding a 12v relay board that’s 16 or 32 channels and integrates with HA but also has its own app as a backup. Also ideally one that can handle 20amps or so.
If it had built in fuses that would be even better
Any suggestions??
looks promising…
Note: I will never put 20A on the relays directly, even on boards, that say to support that. If it goes wrong, expensive board is dead.
I will just buy 32 contactors, and let the board switch the contactors, so the main load is separated from the controller board.
Some similar board in action using contactors… https://de.aliexpress.com/item/1005006873911814.html?algo_pvid=fe444305-c2f7-4ec0-b398-2ae9c1639c85&algo_exp_id=fe444305-c2f7-4ec0-b398-2ae9c1639c85-20&pdp_npi=4%40dis!EUR!558.33!390.83!!!601.65!421.15!%40211b615317240793760741124e9183!12000038588469298!sea!NL!0!ABX&curPageLogUid=nqYY8br85VaI&utparam-url=scene%3Asearch|query_from%3A
There is a good chance that your expensive house is burnt.
Don’t trust amps declared by aliexpress sellers, they might be rated for that current for some milliseconds…
The following examples all run on 12vdc input, and all have processors which can all be programmed with Tasmota or ESPhome firmware providing both HA integration and a standalone web server for control. None meet all your requirements, but if there is an area you can compromise, or maybe mix and match, consider:
Hmmm I can’t see this product, it appears both your AliExpress links are to the same KinCony board which only has 7A relays and “dry contact” inputs. I’m guessing the second link was meant to be a different product?
That’s the meaning of the words “Some similar”, is not it? 
as @peterxian said, your best bet is Kincony. And my tip still stays - combine with conctactors for safety and reliability.
I have this coming today and will at least play around with it. There’s a few spots where i’ll want to add some switches outside the main area so this works for those

Kincony looks perfect, but then I need to add contactors and then fuses which isn’t ideal in a tight space (behind a cabinet). I also haven’t found a spot to buy it and definitely not in the US.
16a would be perfect as I can run 15a fuses which should handle basically everything. Ethernet is ideal too as I’m assuming it’ll use less power than wifi and less to deal with. Power isn’t a huge issue as I have 5kw solar on the thing but still trying to keep my idle load down for this project to 10ish watts.
Also am I correct in assuming I want ESP32 vs ESP8266 for this? I’m very concerned about stability/ reliability and less concerned about price.
Then you always want ESP32.
Difference is about $2, but I would choose Esp32 even if it was costing $10 more…
