Hello,
I’m finally taking the time to work on creating homemade temperature probes (to start with), based on ESP01 and DS18B20 sensors (OneWire). I know that this type of ready-made probes already exists, but the pleasure of DIY is not there!
Is it planned in v4 of Gladys to integrate a graphical element displaying data of this type (temperature, humidity, etc.), as is the case for the « weather » element?
Once everything is functional, I will let you know!
Have a good end of the day,
Jean
Great project!
Why not, it’s a good idea! On my side, I have a few ongoing projects on v4 (Z-Wave, etc..) if someone is motivated to propose a PR, I’m interested 
maybe this will help I just read this:
Hello @bjm and thank you for the suggested link! The project is indeed very interesting, I already have a RPi Zero W in the garden, to control the automatic watering (it controls relays that control electro-valves connected to the pump I have at the bottom of my well …). The proposed developments in the comments show all the interest that many people have in home automation, and this is just the beginning … We just need to make things simple and affordable. My idea is precisely to find « low-cost » solutions to my needs, while making them as simple as possible in terms of integration and use (PS: @pierre-gilles, I’m expecting a lot from the v4 of Gladys 
…).
Not finding a ready-made solution, I am currently developing the code for a temperature probe (in a first step) that can easily evolve later (humidity, hygrometry, etc …) sending data via MQTT. All of this, working autonomously (with 2 1.5V batteries or rechargeable battery via solar panels, for example). I am looking for the energy autonomy of all the « gadgets » I set up to avoid having to pull power cables everywhere … In short, as soon as I have news to share, I will of course be happy to share it with you
