Need recomendation

[silicondt]

Hello we have a project that will have 25 mag locks.
When you provide 24v the mag lock will engage.
These will lock and unlock wine cabinets.

Each mag lock has two outputs. A door sensor and a mag sensor.
These outputs are dry closes contact.

We will be running 6 conductor wire to each mag lock.

So basically we need 25 relays, and 50 dry contact inputs.

We want to use "home assistant". so the board needs to integrate well with it.

Would the KC868-AIO be the best board for this?

Bonus question - I see I can add temp sensors. Can I only add two? We need 4 total.

Thanks!

1. Yes, KC868-AIO is suitable for you. it have 32 channel mosfet output, you just connect with two KC868-E16v2 extend relay board is ok.
2. About 4 temperature sensor, it's OK, because home assistant support use one GPIO for multi sensors, such as DS18B20. we have tested, 12pcs of DS18B20 work with one GPIO also is work well. You just config it by ESPHome.

Можно ли удлинитель датчик температуры проводом для интернет 4х2х0, 5 на 40 метров? Если соединить 4 проводка в один. Таким образом получится два проводка по 2 мм2.

what sensor? DS18B20 sensor?
