Waterproof Temperature Sensor With ESPHome + Home Assistant!

Hi Everyone, In this video, I show you how to build a waterproof temperature sensor that works with esp home and home assistant. I will be using this to monitor my aquarium temperature. If you enjoyed this video, please leave a like and hit that subscribe button!!

I could not get this to work as the ESP board would not come online after entering the wifi credentials. I kept giving up but really wanted this to work. I finally figured out the issue which was not with the board or this tutorial, it was an issue with my router setup. There's some setting in there that wont allow the board to connect, I confirmed this by connecting to a different router, one i use as an access point which is on the same network. It connected straight away and the rest of the tutorial worked perfectly. So if you have that problem where the board doesn't come 'online' after the install, try looking at your router settings! Thanks guy, this is such a good ESP/home assistant project and a really cheap way to have many temperature sensors and then have those sensors trigger automations for whatever your trying to do. I now have my 4 aquariums monitored in home assistant with alerts to tell me if something is not right. That cost me under around $12usd for 2 boards, the jumpers and 4 sensors from Ali express. Just for fun I'm going to set one up with some LED lights on a solar controller with battery in my chicken coup so i can monitor the temp in there. Why? Because i can.

Does your router have 2.4ghz turned off? These esp8266 boards are not 5ghz capable. They will only connect via 2.4ghz.

First of all thank you! Your video helped show me how the resistor is soldered between the data and power wires. And I loved the box you used! Going to order one to help make it more presentable. Im using this for the same thing, except I’m monitoring 4x tanks per ESP board and using HomeAssistant to flick a Kasa outlet for my heaters. I’m going to share this with my fellow fish club members, so easy! :D

LOVE IT! Thanks so mutch!, this is exacly what i was looking for to monitor the in and out line temperature for my heat pomp for my pool

[@BryansLifeStuff]

So much stuff out there. I happened upon your video and it got a whole lot easier. Thank you so much for taking the time to share your experience. Much appreciated!

[@daveocatnz]

awesome! i lost a bunch of fish due to a heater malfunction, or i unplugged it and didnt notice till it was too late. After playing with wled and esp, im looking for my next project, and this video happened to be recommended, perfect! Im looking to setup 4 of these for 4 tanks and my home assistant will send notifications if temp drops.

Thanks for sharing, really helpful. Appreciated

hello When the temperature sensor is connected to ESP 32 and I use it with a battery or a good mobile charger or an industrial switching source, the device works without problems, but after switching from a switching source in a place where single-phase and 3-phase electric motors work. They say that sensor information is not received. What do you think I should do?

[@jaroslavsimecek8452]

Hello, Perfect video. I need to make sensor for my smoker. I am planning to use the Dallas for the smoker temperature but need second sensor which will be meat sensor. Do you know by any chance if there is any I can use with one Dallas the same way you are using 2 Dallas's? The smoker is like 150ft from home. I am afraid it might be too far for this board. What do you think? Would you please have any suggestions? Thank you very much!

I don't know about different sensor types, but I did a quick google search and others have gotten the Dallas DS18B20 sensor to work over 100ft of CAT 5 wire. Heres a link to the page. forum.arduino.cc/t/ds18b20-length-of-wires-limitation/496404

Great video, thanks! I’m planning to use this to get a window a/c to run cooler. I need a temp probe for ambient, and one up against the cooling fins to ensure they’re not cold enough to be icing over- your example is perfect. Last piece is applying heat to the a/c’s temp probe when I want it on, do you have any ideas or pointers for that? I’ve seen people use a lightbulb but figure there’s a more elegant solution using a resistor, just never attempted something like that before.

[@michielhereijgers6136]

Thanks for the great video. Is there a limit on how many sensors you can add?

[@melonmonkeygarage7735]

I haven't hooked up more than two myself, but I was reading online that people have gotten 8 to work with ESPHome

[@BillyF2LJeffs]

What if you have a very long probe cable? I have a 15m cable connected to a wifi temp sensor right now but want to change it to an ESP board to get faster reporting. Do I still need the resister if I have this length cable?? Thanks.

[@ArnodeLange]

can you explain why it needs the resistor.... and how did you get to the point how strong the resistor needed to be

[@lance3529]

It says on the ESP website under Dallas Temp sensor. "The 1-Wire bus the sensors are connected to should have an external pullup resistor of about 4.7KΩ. For this, connect a resistor of about 4.7KΩ between 3.3V and the data pin. Values ± 1KΩ will, in most cases, work fine as well, if you don’t have massively long wires."

nice
