TLC2206 Tuya Smart Life Mobile APP Wireless WiFi Remote Ultrasonic Contactless Indoor Waterproof IP67 Liquid Water Oil Fuel Level Tank Monitor Sensor Controller Automatic Alarm Indicator

They're paid for notices for high and low. It's absolutely worthless. It's so busy showing cute little icons and giving you points, and all the silliness that you can imagine, yet it will not show me low level notices.I paid ten dollars as a test. Do not bye the warnings. Customer service is a bot that knows nothing.

The price and the product idea are great. Upon the initial examination the product execution looked excellent. The circuit board has a nice thick conformal coating intended to allow the product to function in humid/wet environment. The circuit board is protected by a screw on cover with a rubber gasket. All look great.After 2 months of outdoor use the product failed. The power supply works fine, the product cover or the power cord port feed-through failed to protect it from a heavy rain fall, resulting in water propagating inside the enclosure. While the amount of water was no greater than about 0.050 in, the conformal coat failed to protect the components from the resultant moisture. Even after drying the circuit board the device has been rendered unable to be seen on the wireless network.

I bought this level sensor for my 1500gal water tank so that I could track use and how well my low-flow water well kept up with my usage. So far it is working really well for me. The instructions are not amazing, but once I puzzled out the app I am very pleased. My tank is well over 50’ from my house, and after setup the WiFi connection has been nice and stable, and the ability to check the level in the tank without hiking out to the tank, climbing up to look in the access port. I had to fiddle with the calibration a bit - distances from the probe/sensor to the full fill line, to the ‘empty line’ just above the pump inlet, etc., but once done its been doing all that I hoped. ALSO - I paired this sensor with a solar panel with incorporated 10,000maH battery that had 9v output option (AMZN product marketed as a trail cam solar battery). This way I can power the sensor without long extension cords out to the tank. I would buy this sensor again.

This device is worthless you can't even set it up to message you through the app and wifi. It requires a $100 per year for unlimited messagiong. You can buy a block of messages but the device will burn through those sending repeated warnings. They do not advertise that a subscription is required otherwise you have to monitor the app to watch the levels. So unless you pay for a subscription the device is worthless. The data is not even accurate enough to be worth the subscription fee. Testing the unit the level jumps around according to the sensor even though actual level stays the same. This will lead to spamming messages from alarms coming on and off so if you buy a 200 message block and assume it should only send you 10 per year. If you have a smaller tank that is close to empty or full it will send constant messages through out the day. For what this device cost the app should at least send messages for free. For how inaccurate the data is the subscription fee is not worth it. There are other units for not much more that do not require a subscription. Don't bother wasting your money on this unit. I will be returning to Amazon for full refund like I am sure just about everyone does after they see what this unit is all about.

This works for me great! I have bought tank monitor to use in my Toronto rainwater tank. My tank is 95 inch high. It seems to be very accurate and completely solves my problem to know when my water supply status.I connected the sensor to my mobile easily.In the setting step,there is full line to sensor level.I set wrong first time so the liquid level ratio didn't show correctly.After following instuction,It works correct.The price is quite good.Maybe because they are original manufacturer. I will order more.

This was a nice addition to my water system to keep an eye on the water tank level. I've used it for about 2 months now and today it decided to stop working on the app. I opened it up to reset and it was flooded with water. There's no way for water to get into it from the outside because it is rainproof and it was never in a situation to be submerged or even have water around it. The lid was wet, the INSIDE of the cable gland was wet, but no evidence of water intrusion. The only option is condensation buildup over time. If I were to buy this again, I would make some adjustments. The button inside needs to be accessible so I would put a tube around it and fill the rest of the container with epoxy or maybe even drown it in hot glue. That way, any condensation will not cause a short in the board. The epoxy coating it comes with is nice but several points on the board are exposed conductors so it needs more protection. I believe this would solve the issue but it shouldn't be a consumer responsibility. The manufacturer needs to drown this thing in epoxy

The equipment does an excellent job but is very susceptible to voltage change, the working voltage range must be 9 V and only 9 V, I have already bought four that for some reason stop working during some power change..I wish they could expand the voltage range in which the device can work.

After a few months the sensor has started to fail/misbehave. The water level starts to flap continuously and also shows its empty when its not.Now it only shows 100 even when it is half capacity.
