Did you try a different power supply?

I've had problems with cheap Chinese USB power supplies.

You might need to put a cap on the power line to the 18b20s. Maybe try shorter wires to the 18b20 to see if that makes a difference.

You can do this without IFTTT if you want. Also without exposing node red to the internet. Alexa will be using the cloud, but it already does. I added this palette to node red: https://flows.nodered.org/node/node-red-contrib-alexa-local Works fine. Add a alexa node to your flow, and then go to alexa ...

Oops, I lied Make a user variable of type time Then, if you can do something like this to create local variables with hours and mins, for example. local thour = domoticz.variables('SpkrStart').time.hour local tmin = domoticz.variables('SpkrStart').time.min user variable is name SpkrStart in the user ...

Define the time as a user variable of type string.

Then you can read it into dzvents

This sounds more like an ESP Easy issue than a domoticz one, although you need to do stuff on both. Did you ask at the esp easy forum? Or search there for threads on the opentherm? Seems like you need to figure out how to read your openthrrm data first. And once you can do that, it should be pretty ...

I don't port forward and get email notifications fine.

I set up a separate email account just for notification since they are free

My primary account requires confirmation so had trouble with that. Separate email is better anyway don't have to worry about email security

Very cool, thanks for this. I've been on the fence for a long time getting an envisalink, this may push me to get one. I was just looking at the page, and it wasn't obvious to me how notification works? I have dzvents scripts already, so wondering if I can create a dzvents script to send a message ...

FWIW, I implemented a sprinkler controller with Dzvents, and I'm pleased with it. I use ESP's running ESPEasy to actually control the relays which turn on the sprinkler valves. I have a front and back, so I have two ESP's (Wemos D1 mini's) to handle this. Dzvents is used to send the commands to turn ...

Its a pool not a pond, but you may get some ideas at least.
PH measurement is discussed, since I don't own a pond I don't know what the other measurements are.

@aleph0 Thanks very much for the long, detailed reply. Your results are very impressive. You should be proud of this system. The issues with acid is why I don't plan to try adding an acid pump. I have a fiberglass pool, and don't have to add acid very often. If I could just automate chlorine, I ...

Aleph Wondering how your system is working? A status update would be great. I specifically curious about how the orp sensor has performed over time. I'm thinking about adding an orp sensor to my pool setup. Currently I have an Wemos ESP like you, but it just controls the pump and heater. For now, I ...

I also used dzvents to create a simple script to notify me when the garage door is open for too long. I created an email account just for domoticz email notifications, and set it up so the emails get forwarded to my phone as text messages. I found that most phone providers will turn emails to texts ...

Wow, you've been busy Danny.
Great stuff, thanks.

I do have one question.
About your works with time, comparing time example.
It looks like the times are one hour apart, but the code appears to be comparing seconds, and saying result will be 60.

Am I missing something?

I'm looking at https with letsencrypt. I tried a while ago to create my own certs on my pi and didn't have much success, so hoping this will go better. If I can get letsencrypt and domoticz working, I would be OK to open one port for controlicz to my pi. But don't I have to give you the letsencrypt ...

So I think I know the answer, but is there any way to not port forward to my domoticz pi? I have openVPN setup on my router, so I have been using that to access domoticz when I'm not home, and it works great. Am worried about security if I open a port for this. I would like to try installing the ...

You should use the wiki

Yes, but as there is no problems for xiaomi app users, only for domoticz users, i doubt they will change the firmware "back for us" :) Maybe if we complain a lot they will fix it. For every actual complaint a company gets, it multiplies it by some number because most people won't bother to complain ...

So I think you're saying I can use my browser to make a http call to set a dummy text switch, and then for example, use that for the temperature for my thermostat. Then I make a bookmark with that http address. I guess the only problem is you would have to edit if you didn't like the default temp ...

So I prefer using persistent variables, it's easier and cleaner, keeps everything together. But I don't know how to update persistent, or even global variables from an app. With global variables, I can update them from my android or wife's iphone app. I've set up things like sprinkler run times and ...
