Welcome. I'm not 100% sure but the docs for the board you linked is for a Pi. I couldn't find any wiring diagrams for the tentacle but it will definitely need a micro controller to work correctly. Esphome is based for ESP micro controllers so you'll need a Node MCU or ESP32. If you can find the I2C ...

I just figured out how to calibrate with the set up. It was right under my nose the whole time. Search UART switch on ESP home for more info. switch: - platform: uart name: "Mid Point Calibration" data: 'cal,mid,7' This creates an switch entity that can be toggled to send the command through wifi to...

Fortunately they implemented EZO sensors on ESPhome so all this programming isn't needed anymore. I'm still running a custom sensor because I like using the Arduino for a pH safety controller. There is an open feature request on GitHub to implement commands to the various EZO sensors using ESPhome. ...

I just started messing with my EZO flow sensor. The plan is to have a flow sensor on the pump outlet. When I call for the tank to drain and the flow stops, the system will stop the pump running and send me a notification. Unfortunately esphome doesn't support the flow sensor yet. I tried to hack it ...

I just got my notification to work through node red thanks to some online help. Change node to the message you want then call service. Change Node set message payload to string "What you want the notification to say." Call Service Domain: notify Service: mobile_app_"id" Leave entity id blank! Data: ...

Do you have the probe sitting in a tank? The first probe that failed was just sitting in the bottom will minimal flow from the air stones. I was able to get it working again by putting it into the flow but the readings were very slow to react and it fell out of calibration after 5 days. I changed i...

What type of maintenance have you been doing for your probe? Are you doing a bleach soak weekly as suggested in the manual or a quick rinse? Storage solutions during res change. Stuff like that.

I've had a problem with using RO water in bottles. I run the machine while I'm doing a res change for the following week. By the end of the week the 5 gal jugs have a slight smell of mildew. Probably not an issue but I decided to switch to a 20 gal RO tank from freshwatersystems.com. I ended up goin...

What were you running before Tasmota? How was your probe installed in the system and what are you monitoring? Was there equipment in the water in addition to the probe? Might be time to jump on that Tasmota train. I just got my WeMos boards in preparation for the change. I'll be adding temp, conduct...

There's been some developments with this situation. One night during an auto pH balance the curve was extremely slow. I open the reservoir to check and found the water cloudy. The pH was at 8.9 causing a precipitation of salts, yet the meter read 6.0. After calibration the meter performed properly t...
