Re: Geiger counter settings

Hi, below is my pulse counter plugin screen. My geiger cirquit produce short positive pulses, no debounce, and they just get registered by the plugin.

Re: ESP Easy Mega MQTT issues

I think you should check the command reference first to find which commands may work through mqtt subscription. As far as I remember, gpio is not among them. However, you can initiate the event with event command, pass any arguments such as gpio# and state and then use it in rules for activation

Re: Solar Power Supply

Here's my voltage detector part, similar to those in Andreas' video. Cuts down at ~2.7V and provides some hysteresis turning on when the bat is charged to at least 3.1V

Re: Geiger counter settings

I get similar functionality using ESPEasy with counter plugin and single gpio. Data is uploaded to mqtt broker every minute, then processed in Node-Red and visualised in Grafana.

Re: Battery goes down WAY too fast on ESP

Based on your discharge graph, you are in the upper part of the discharge curve which is very nonlinear. So 50mV drop in this region is basically nothing to worry about, you may then experience weeks at 3.7V without a sign of depletion. In fact, voltage is not a good indicator unless you personally ...

Re: MQTT Import with values inside {}

I'd use Node-Red to convert JSON data to whatever ESPEasy could accept and pub it back into different topic.

Re: Temperature sensors - which are most precise?

Precise metering has a (high) price. Don't expect a BME280 from Aliexpress (usually a cheap copy of the genuine Bosch sensor) to be as accurate as the Bosch type. I wouldn't be so sure about someone's ability to copy Bosch's MEMS technology. Even if someone in China could mimic it, I don't see a ma...

Re: Solar Power Supply

Even better will be using switched charger such as TP5000. Even though it doesn't have MPTT, it can catch low sun condition provided the panel OC voltage is between 5-6V
