How to log fridges temp remotely and send mail if alarm ?

#1 Post by tparvais » 29 Jan 2020, 23:51

Hello

I’m supporting a non profit organisation having a Chalet in Alps that welcome kids during winter.
We have several fridges for food. The chalet occupancy is not constant.

I need to monitor the temperature of several fridge remotely via internet and get a mail if temperature reach a level.

Last year I installed ds18b20 and one esp with Espeasy. But the problem was to access it from internet and possibility to send mail (I need ssl...)

Any idea on a free cloud service that I can use easily sigh espeasy without installing domoticz or whatever locally ?

Thank you

If you use Gmail you can use the server: aspmx.l.google.com

Only thing to know though, you can only send to other Gmail addresses (or G suite).

But, you could have an account which would have a rule to forward the received email to an "external" address.

See, restricted SMTP options here:

Thank you for this trick

And to be able to chart temperature without having my own
Server , any idea ?

Easyiot could be a solution but not sure there is a plug-in
For this ?

I mean beside being able to get alarm by email , I wanted to save temperature logs somewhere but I don’t plan to install my own server over there (Domoticz ...)

Is there a public free solution for that ?

For google mail , I saw I need to record ip address at gmail . My Ip is Dynamic and will be difficult to do. Is this also compatible with dyndns?

3 years ago I installed a DS18B20 temp sensor in my wife's florist shop main fridge.

ESP Easy device publishes the data to thingspeak

https://thingspeak.com/channels/177708

Then I enabled the thingspeak React (Apps/React) to tweet me in event temp is lower than x or higher than Y

Every once in a while when they "clean" the fridge I get a high temp alarm tweet

You could use the 16 variables inside the unit and have them graph the latest 8 days highs and lows or so...? HTML the chart inside the email.

Regarding IP, I wouldn't know.

I don't quite understand how temperature is related to IP.Mainly a fixed mailbox.You can solve the problem

I solve the problem by moving to mqtt/influx/grafana and using grafana alert notification agent to send email when temperature is too low . Works perfectly

Another solution would be using IFTTT.

Basically ESPeasy sends a HTTP request to https://ifttt.com when temp too warm.
IFTTT reads the HTTP request (Webhook) and sends a mail or calls your phone or restarts your Tesla... you get the idea :D

Maybe IFTTT even has a direct connection to thingspeak.
