@magpern said in MyQTherm - replace IQTherm heating thermostat:
I actually am thinking somewhat in the line of discontinuing mysensors network. It is to much, hacks and tricks, and I forget everything in between sessions.
I gave up more than once, also over period of years. Recently I came back again and decided to focus on the heart of the issue, getting my radios working and once you get over that, it starts to get fun again.
I can respect if you already moved on to something else. I even cheated on MySensors and installed some 433 mhz devices too , just to get something working. You have to keep your interest in HA alive in the meantime. But the reward is great when you get MySensors working.
There are "easier" solutions like Tasmota, 433mhz, etc. but not as customizable as MySensors. MySensors is for when you outgrow those other solutions and need something more custom.
I like those relays. Is that 3 different switched outputs? One thing I always liked about european wall switches is that they give you more room for components. I would like to use a similar type of relay for my in-wall switches, but with the way US single gang wall boxes are, there is a pretty narrow space constraint. I might be able to fit it if I did away with the thermal fuse, but I don't want to give up tat bit of added safety just for that.
I would think that the "heavy lifting" of regulating the actual output power of the charger would be a function of the charge controller itself? Maybe you could tie into / control that somehow with your own microcontroller as brain / interface? Maybe they expose some API, serial, or other method of interfacing with their hardware?
What are/were you using for charge controller?
Also, what is "CT" in this context?
I have read a bit here and there about solar (and related moving around and controlling of power, eg. batteries, charge controllers, etc...), as it is something I plan on doing "eventually" although I have no direct experience as of yet. So I will be following this thread with interest.
I see a lot of "!TSF" and "NACK" which seems to be radio communication problems.
That's MySensors related and can be related to many things, from soldering problem to power / capacitor issues.
In MY_DEBUG mode you should see your temp/hum printed on serial every ~15s so there is something wrong there, either wiring or a code issue.
Ty with the example included with the library "i2c_SI7021.h", without any MySensors related stuff, to see if your sensor is detected. You should see temp/hum on the serial.
@kalina, Thanks. So it will not work for my configuration. Wall switch (push button) is already installed. No possibilities to draw more electrical wires.
Moreover, if i put the board near the light, i have just the Neutral and the return wire from the wall switch. No Live wire to power on the mysensors board.
I think in my ase the best way is to manage everything in my garage in the electrical main board where all the wires are mapped. I can get L + N for mysensors power supply. And i can continue to reuse the original wall switch independently of the Mysensors board.

Hi, unfortunately I don't have time and patience for doing BOM's on all of my projects but in this case it's not very hard as the external component count is greatly reduced by using the NRF51822 RF SOC which is a PTR5518 module from Aliexpress. Other than that there is the Microchip touch sense controller - MTCH105 and the usual smd resistors(0603) and caps. Other than that you're not forced to use and solder the onboard dc-dc converter so you don't have to worry about those components - you just need to solder the 3V_EN jumper to use the Livolo 3V output coming from the main relays/power supply board.
