-# WiFi-remote-for-Bestway-Lay-Z-SPA (including 2021 year model)
-## Hack - ESP8266 as WiFi remote control for Bestway Lay-Z spa Helsinki<br>
-### Disclaimer: As mentioned, this is a hack. If anything breaks it breaks and it's your fault.<br>
-### Caution - Unplug mains power to the pump before trying to replicate this hack, or you can die! <br><br>
-
-### Features:<br>
--Watch the temperature and status from your browser.<br>
--Custom text on the SPA pump display.<br>
--Custom sound instead of just beeping is possible.<br>
--OTA: Update firmware over the air. Super convenient when mounted inside the pump.<br>
--Simple to build. No hardware changes needed on the SPA pump. Just remove the display, disconnect the 6- or 4-pin ribbon cable and plug it into this device.<br>
--Timer for chlorine. Hit the button on the webpage when adding cl and it will count the days for you.<br>
--Timer for filter change. Pulled from @Bankaifan.<br>
--Electricity cost estimation and more<br>
--MQTT support! I have it installed and working with a Raspberry Pi 4 B with Home Assistant. Thanks to faboaic and 877dev for MQTT support! Now you can control the SPA from Home assistant etc.<br>
--Schedule events like heater on/off at specific dates, with repeat functionality.<br>
--Listen to input signal on one pin and trigger a signal on another pin on desired events. For instance let solar panels turn on/off heater.<br>
-<br>
-### BOM:<br>
--ESP8266 NodeMCU 1.0 (This version is NOT for ESP32)<br>
--8 channel bidirectional level converter<br>
--6 or 4 pin male header (0.1 in spacing) or better: JST-SM Housing Connector<br>
--6 or 4 pin female header (JST-SM Housing Connector)<br>

+> #### Caution
+> Pull out the mains plug before before modifying hardware, or you can die!
+
+#### Features
+- Control buttons, watch the temperature and get current states from your browser.
+- Custom text on the SPA pump display.
+- Custom sound instead of just beeping is possible.
+- OTA: Update firmware "over the air". Super convenient when mounted inside the pump.
+- Simple to build. No hardware changes needed on the SPA pump. Just remove the display, disconnect the 6- or 4-pin ribbon cable and plug it into this device.
+- Timer for chlorine addition and filter change. Hit the button on the web interface and it will count the days for you. (@Bankaifan)
+- Electricity cost estimation and more..
+- MQTT support! Now you can control the SPA from Home Assistant, OpenHab etc. (@faboaic, @877dev)
+- Schedule events like heater on/off at specific dates, with repeat functionality.
+- Listen to input signal on one pin and trigger a signal on another pin on desired events. For instance let solar panels turn on/off heater.
+
+#### BOM
+- ESP8266 NodeMCU 1.0 **(NOT for ESP32)**
+- 8 channel bidirectional level converter
+- 6 or 4 pin male header (0.1 in spacing) or better: JST-SM Housing Connector
+- 6 or 4 pin female header (JST-SM Housing Connector)
