I have a #S9 #antminer with only 1 working #hashboard.
But it also reduces #hashrate down to 200 Gigahashes after about 5 minutes running. 
It comes with an error message 
ERROR bosminer_hal::sensor: Sensor hb7[ii_hwmon::tmp451::TMP451]: read failed: I2C error: general error Hashchip: no response for read_register(reg=0x20) from chip One(61)

It means on Hashboard 7 (connector 7 of control board) sensor #TMP451 has a read fail. 
There is a #I2C (bus) error. I am not sure what "chip One(61) really means, but I guess One means because it is the only tmp451 chip and 61 stands for the location (it is located next to Hashchip 61). 

I found a few informations in different forums and on #zeusbtc.com (what is an awesome library for fixing mining hardware) 

I unsolderd the #heatsink of hashchip 61 a found the senor. It looks pretty dirty (see pic) so I cleaned it an mounted the heatsink again. I will test the #miner tomorrow. 
Maybe I am lucky and that was it. If not I will first try to run it with reduced power. 
The (first) goal is to have at least one hashboard running stable.

 Nothing is constant except change. 
I am not doing any electrical works in my #greenhouse. 
I rather have made the rest of my garden ready for winter. 
But I tried to #fix my #S9 #antminer
I show details in a second note 

 This weekend I will equip my #greenhouse with 2 additional switchable sockets and prepare cables for a #grow lights. Maybe you can recommend some grow lights or give some tips?
I also try to fix my #s9 #miner. At least one #hashboard with a malfunction temperature sensor. 

If I have got some time left, I also want to post some history of my projects, myself and my motivations. 

#react #comment and/or #zap for more.

 Hi #nostr,

you might wonder why #organgery, if I don´t even own one??

It´s my #dream and #vision and it is a #symbol for my #values. 
My strategy is to identify with what I want, not just what I have.
This keeps me motivated and on track

#introduction 

 I really love the light effects of my S9 #miner in my #greenhouse. 
I build it this year and so far it is #tomatoes (and S9) only. Anyhow I will add some #grow lamp and sensors to it within the colder seasons and more different #plants next year. 

I bought the s9 very chip but with a high risk that it is not working 100%. And turned out 2 of 3 #hashboards have malfunction hash chips and the other one has a problem with one temperature sensor. So I am currently working on a fix of the temperature sensor first. 
So time to train my rusted #solder skills.

 Hi nostriches, 

I want to start this journey sharing my ideas and projects searching for solutions and knowledge that might be relevant in a bitcoin world.

My current projects are heating my pool with a S19 antminer and heating my greenhouse with a S9 antminer and of course my smart home with intelligent energy flow. 
Future projects will focus on nostr, lightning, bitcoin.

If you are interested in details to the projects and the progress please give me a reaction, comment or zap.

I hope I can learn a lot of this community and find some interesting people.
